Translation of "Melt mixing" in German

A molding compound according to example 3 was produced by melt mixing.

A combination of a dry mixing method and a melt mixing method is also conceivable.

The moulding composition is produced in the melt by mixing the individual components.

Mixing apparatuses to be used for such a melt mixing process are preferably single- or twin-screw extruders or Banbury mixers.

The action of ultrasound and pressure causes the fibers to melt with the mixing zone.

Generally, mixtures SKMF, such as mixtures SKMP, are preferably prepared by melt-mixing.

The polymer composition is produced out of the individual components, preferably by melt-mixing in a kneading aggregate.

The polymer composition of the invention is preferably produced from the individual constituents by melt-mixing in a kneading apparatus.

The polyamide composition of the invention is preferably produced from the individual constituents by melt-mixing in a kneading apparatus.

In this process, the oligourethane electrolyte, which may contain methylol groups, is preferably dispersed in the form of the solvent-free melt simply by mixing it with water.

Furthermore, for a comparable content of conductive carbon black, the product obtained by the process according to the invention also exhibits substantially more advantageous flow characteristics than does a product obtained by conventional melt mixing.

Process for the preparation of the thermoplastic compositions as claimed in claim 6, wherein a finely powdered mixture of components (B) and (C) is fed into the thermoplastic melt in the mixing apparatus.

However, an alternative procedure is to introduce the components successively and homogenize the melt by mixing it.

The mixtures may be prepared by the methods normally used for mixing plastics, for example by compounding in the melt, by mixing of powders, by co-extrusion, by mixing of solutions and evaporation, by mixing of latices (or other dispersions) and co-precipitation.

However, the starting polymers may also be blended in the melt in such mixing units as, for example, extruders, internal kneaders and mixing rolls.

According to the invention, the blends are prepared by simple melt mixing, the temperature and mixing time required depending on the nature, proportions and molecular weights of the components used as well as the size of the batch.

These moulding materials are advantageously prepared by mixing these components at temperatures in the range from 220° to 350° C. in the melt in conventional mixing apparatuses, such as, for example, kneaders or extruders.

The thermoplastic processing then follows by homogeneous blending in the melt using heated mixing units at a suitable temperature, for example 150° C. to about 300° C., in kneaders or preferably in extruders, for example single-screw or multiple-screw extruders, or optionally in extruders with oscillating screws and shearing pins (for example, in a BUSSCO kneader).

The mixtures may also be prepared in the melt on mixing rolls, in screw extruders or in kneaders.

Thermoplastic treatment then follows by homogeneous blending in the melt using heated mixing units at the temperatures suitable for this, for example 150° to about 300° C. in kneaders or preferably extruders, for example single- or multiple-screw extruders, or optionally in extruders with oscillating screw and shear pins (for example, in a BUSSCO kneader).

Then a mixture of bioactive substance and, where appropriate, a release agent is metered in and homogenized with the melt in another mixing region.

Polyolefins which conform to the description under 2) can either be prepared directly in the polymerization or are prepared by melt-mixing in an extruder or compounder.

The preparation of such masterbatches can be carried out by any known technique: for example, by intimate mixing of the colorants with the vehicle in the melt in suitable mixing equipment, examples being dispersion kneaders, Banbury kneaders and screw kneaders, e.g., twin-screw extruders.
