Übersetzung für "Spatial stream" in Deutsch

Specify the minimum number of allowed spatial streams.

Specify the maximum number of allowed spatial streams.

Like all AC1900 routers, data is transmitted on three spatial streams.

In principle, the spatial streams add a 3rd dimension—space—to the existing frequency-time matrix.

In the factory settings, the device automatically has the spatial streams turned on in order to optimize use of the radio system.

In this case the remaining starting monomers and the remainder of the initiator system are customarily metered in via spatially separate streams, the starting monomers being preferably added in the form of an aqueous emulsion which contains essentially the remaining amounts of surface active substance and of aqueous dispersion medium.

Of course, the various possible, generally spatially separate, feed streams can be mixed with one another immediately before entry into the polymerization vessel.

The free radical polymerization initiators are advantageously added in a spatially separate stream, and their addition advantageously takes place essentially synchronously with the addition of the monomers to be polymerized.

In the latter case, the process of the invention and the process for preparing the starting dispersion II can merge smoothly, in particular when the aqueous starting dispersion II is prepared employing the stream addition process, in which part of the polymerization batch is introduced as initial charge and heated to the polymerization temperature and the remainder is then added to the ongoing polymerization in a stream or spatially separate streams.

In the latter case, the two emulsion polymerization processes can merge smoothly, in particular when the aqueous starting dispersion II is prepared employing the stream addition process, in which part of the polymerization batch is introduced as initial charge and heated to the polymerization temperature and the remainder is then added to the ongoing polymerization in a stream or spatially separate streams.

Advantageously, prior to the start of the free radical emulsion polymerization of the invention the polymerization vessel contains only some of the free radical polymerization initiators, whereas the remaining free radical polymerization initiators are in general added to the polymerization zone at the start of the free radical emulsion polymerization of the invention via a spatially separate stream, which addition preferably takes place synchronously with the addition of the monomers to be polymerized, but in general will take longer than the latter addition.

Preference is given to the feed process, in which part of the polymerization batch is introduced as initial charge and heated to the polymerization temperature, and partially polymerized, and then the remainder of the polymerization batch is fed to the polymerization zone continuously, in steps or under a concentration gradient, usually via a plurality of spatially separate feed streams, of which one or more include the monomers in pure or emulsified form, while the polymerization is maintained.

The addition of the monomers and/or of further additives can again be made by way of two or more spatially separate feed streams, in pure or emulsified form, continuously, in stages or with the superimposition of a concentration gradient, while maintaining the polymerization.

Preference is given to the feed process, in which a portion of the polymerization mixture is introduced as an initial charge, heated to the polymerization temperature and then partially polymerized, with the remainder of the polymerization mixture being supplied subsequently to the polymerization zone, usually by way of a plurality of spatially separate feed streams of which one or more comprise the monomers in pure or emulsified form, these feed streams being supplied continuously, in stages or under a concentration gradient, during which the polymerization is maintained.

A preferred procedure is initially to charge to the reactor a portion of the polymerization medium, which may include a portion of the polymerization batch, to heat this initial charge to the polymerization temperature, to carry out an initial polymerization if desired, with the formation of a seed latex, and then to supply to the polymerization zone the remainder of the batch, usually by way of two or more spatially separate feed streams of which one or more may contain the monomers in pure form or in emulsified form, these feed streams being added continuously, in stages or with the superimposition of a concentration gradient and while maintaining the polymerization.

Preference is given to the feed process, in which a portion of the polymerization batch is introduced as an initial charge to the reaction vessel, heated to the polymerization temperature and then partly polymerized, after which the remainder of the polymerization batch is supplied to the polymerization zone normally by way of two or more spatially separate feed streams of which one or more contain the monomers in neat form or in emulsifying form, the monomers being supplied continously, in stages, or under a concentration gradient, during which the polymerization is maintained.

Preference is given to the feed stream addition process in which a portion of the polymerization batch or else a polymer seed is introduced as initial charge, heated to the polymerization temperature, incipiently polymerized and subsequently the rest of the polymerization batch is fed into the polymerization zone, usually via a plurality of spatially separate feed streams, of which one or more contain the monomers in pure or in emulsified form, continuously, stepwise or with superposition of a concentration gradient while the polymerization is maintained.

Preference is given to the feed process, in which a portion of the polymerization mixture or else a polymer seed is introduced as initial charge and heated to the polymerization temperature, polymerization is begun, and then the remainder of the polymerization mixture is supplied to the polymerization zone during ongoing polymerization, continuously, in stages, or subject to a concentration gradient, usually by way of two or more spatially separate feed streams, of which one or more comprise the monomers in pure or in emulsified form.

Preference is given to the feed process, in which some of the polymerization batch is introduced as 40 initial charge, heated to the polymerization temperature and then initially polymerized, and then the remainder of the polymerization batch is supplied, in the course of continuing polymerization, to the polymerization zone continuously, stepwise or under a concentration gradient and usually by way of a plurality of spatially separate feed streams, of which one or more contain the monomers in pure or emulsified form.

Preference is given to the feed process, in which a portion of the polymerization batch is introduced as an initial charge, heated to the polymerization temperature and subjected to initial polymerization, and then the remainder of the polymerization batch, usually by way of two or more spatially separate feed streams of which one or more comprise the monomers in pure or in emulsified form, is supplied continuously, in stages or with superimposition of a concentration gradient to the polymerization zone, during which the polymerization is maintained.

Preference is given to the feed stream addition process in which part of the polymerization batch is introduced as initial charge, heated to the polymerization temperature and polymerized incipiently and then the remainder of the polymerization batch is added to the ongoing polymerization continuously, stepwise or with superposition of a concentration gradient, usually via a plurality of spatially separate feed streams, of which one or more contain the monomers in pure or in emulsified form.

In fact there can be a smooth transition between the two emulsion polymerization processes, in particular when this initial charge portion of the aqueous dispersion of the starting polymer is prepared employing the stream addition method, in which part of the polymerization batch is introduced as initial charge and heated to the polymerization temperature and the remainder is then added to the ongoing polymerization in a stream or spatially separate streams.
