Monomer linkage

The mixture of metallocene and co-catalyst is soluble. Its active center, which is chiral, induces with a very low rate of defects only one type of monomer linkage ( single site catalysts )- That is why high activities (some 1,000 kg polymer/g...

These PMR findings prompted us to undertake a detailed sequence distribution analysis of poly(isobutylene-co- pinene). Sequence distributions can be expres d by the run number/ , i.e the average number of hetero-linkages per 100 consecutive monomer linkages in a copolymer chain (2i). 

Synthesis and Application of Polymers Bearing Interlocked Structures Used for Monomer Linkage... 

They can present a wide variety of structures in relatively short chains. The multiple possible monomers, linkages, and branching patterns allow a vast, but specific vocabulary.

Work by Rees (3) shows the various geometries of the monomer linkages for the poTypyranosides. When glucose polymerizes. Cl is always involved, and the linkage is to the 02, 03, 04 or 06 of the adjacent monomer. The relative angles of the Cl-01 bond with the Cn-On bond in the same monomeric unit determine a catagory of shapes that the polymer can acquire. 

The use of alpha amylase on starch produces a depolymerized starch. The enzyme, cycloamylose gluconotransferase, is responsible for production of cycloamyloses. Biological modification is advantageous as enzyme reactions are often very specific, recognizing subtle variations in the polymer such as a particular monomer linkage or an or conformation.

An example of monomer linkage with termination is free-radical polymerization. 

The other class of molecules that self-reacts consists of monomers that readily form polymers—often these are alkenes or dienes. The polymerization process is usually free-radical generated and with polymeric products sometimes involving thousands of monomer linkages that produce... 

The formula shows that the helical conformation of the chain is imposed by a U-form geometry of the monomer linkages. Amy lose (1,4-linked a-D-glucopyranosyl residues) also has such a geometry, and hence a helical conformation ... 

For monomer linkage without termination, the narrowest distribution occurs in the BR, since all chains are growing throughout the reaction and the effect of constant reaction... 

An example of monomer linkage with termination is free radical polymerization. An example of monomer linkage without termination is ionic living polymerization or (in the ideal case) controlled radical polymerization.
