Translation of "Reactive site" in German

Monomer or polymer molecules with at least one reactive site are suitable as a core molecule.

In the one-pot reaction, the presequence is eliminated and the C peptide starting with Thr (B30) is cleaved out, so that the C-terminal end of the B chain is formed by lysine which is present as reactive site for the enzyme-catalyzed coupling reaction.

The reactive site for the addition of propagating free macroradicals moves away from the surface in the course of the polymerization.

It inhibits, in a fast reaction, plasmin whereby in a fast phase the C-terminal region of alpha-2-antiplasmin binds reversibly to the lysine-binding site of plasmin and, in a second step, the serine residue of the active site of plasmin reacts with the reactive site Arg-354 - Met-355 of alpha-2-antiplasmin.

Surprisingly, establishing the R1-group, i.e., the coupleable silyl group or the Diels-Alder group on the leaving-capable R-group of the RAFT agent (R-group approach, see FIG. 3) is found to have the following advantages: The reactive site for the addition of propagating free macroradicals moves away from the surface in the course of the polymerization.

For getting ready for the separation by affinity chromatography in working step (c), the nucleic acid fraction (mostly DNA) or, however, the protein or peptide fraction is coupled to inert carrier material, as far as possible by covalent bonds, to functional chemical groups, without this being responsible for the blocking of reactive bonding sites having a specific effect.

Surprisingly, the acid halides required in accordance with the invention are formed under such mild reaction conditions that there is no undesirable co-reaction of other reactive sites of the parent monounsaturated or polyunsaturated BNC-structure.

In the case of non-modified fluorinated elastomers, that is to say which contain no particular reactive sites, these crosslinking reactions require drastic conditions, which means that the crosslinking is difficult to control and the fluorinated polymer may become damaged.

To avoid this, reactive sites, so-called cure sites, at which crosslinking can be carried out selectively and under milder conditions are introduced into the polymer chains.

The 9(11)-ene-20-carboxylic acid halides which are required in accordance with the invention may surprisingly be formed under extremely mild reaction conditions under which there is no undesirable co-reaction of other reactive sites of the parent polyunsaturated BNC-structure.

As already mentioned, the 9(11)-ene-20-carboxylic acid halides required in accordance with the invention are surprisingly formed under such mild reaction conditions that there is no undesirable co-reaction of other reactive sites of the parent polyunsaturated BNC structure.

For this purpose, for example, a carrier material containing activated ester functions is suspended in an aqueous buffer solution, mixed with a solution of the monoclonal antibody, then unbound monoclonal antibodies are washed out and unoccupied reactive sites of the carrier material are blocked.

Another starting point for introducing compatibility between polyphenylene ethers and other polymers consists of incorporating reactive sites in the polyphenylene ether even in the stage of oxidative coupling by adding suitable functionalized comonomers, which can react with other polymers when blended with it.

Both reactive sites are suitable for the formation of simple chemical modifications, particular significance again being attributed to those derivatives which do not impair the desired body compatibility and/or resorbability of the materials through the metabolism.

For the preparation of aqueous, heat-curable curing materials with extraneous cross linking agents, it is possible to mix, for example, 60 to 95 parts by weight of the vehicle, based on the grafted epoxide resin, with 5 to 40 parts by weight of a conventional cross linking agent, such as a partially or completely etherified amine-formaldehyde condensation resin and/or a partially or completely etherified phenol-formaldehyde condensation resin and/or a blocked polyisocyanate with at least 2 reactive sites per molecule.

In the process, the disperse surface of the noble metal electrodes enables homogeneous growth of the polymer during the electropolymerization, since many reactive sites, uniformly distributed over the entire macroscopic electrode surface, are generated.

Corrosion inhibitors are in fact chemisorbed at reactive sites on the pigment surface, making these sites impervious to water.

It has been established that these reaction products add formaldehyde not only on the reactive sites of the phenol, but also on the urea groups formed through the reaction with the semi-blocked diisocyanate.

However, due to the high cross-linking density, which may be too high for some applications, as well as in order to increase the dissolution rates of the polymers in the body, fewer reactive sites, i.e. up to 50, up to 20, or up to 10 vinyl ester groups, per monomer molecule are also preferred as groups R 1 in the case of biopolymers.

The client, WIRTSCHAFTSBETRIEBE BAD HERSFELD GmbH organised planning workshops to consult the people of Bad Hersfeld about reactivating the site.

In a preferred embodiment, esters function to convert the protected functionalities (S) into reactive coupling sites (K) which, after the first generation for example has been prepared, are transformed by hydrolysis into active carboxyl groups which can then be reused in UGI-4CRs.
