Heterocycles polymerization

Generally, the vinyl heterocycles polymerize under the influence of a radical initiator, but, under such conditions, thiols react with 1-vinylpyrroles to give the expected addition products (77KGS1636). 

The reduced probability of side reactions enables some heterocycle polymerizations to proceed by a living mechanism. 

The organization of the book follows a logical sequence After a thorough presentation of basic thermodynamic principles and the Jacobson-Stockmayer cycliza-tion theory, the authors discuss in depth all kinds of aspects of the various heterocyclic compound classes. In addition to detailed discussions of mechanisms, many other facets of heterocyclic polymerizations are treated, e.g., monomer synthesis, contemporary research trends, industrial significance. The treatise ends with an excellent up-to-date discussion of random, block and graft copolymerizations of heterocyclics. 

In contrast to the heterocyclic polymerizations, (TPP)AICI does not initiate polymerization of methacrylates [76] and me-thacrylonitrile [77], whereas (TPP)AlMe initiation requires irradiation by visible light. These extremely slow polymerizations are also accelerated by addition of...

Certain heterocycles polymerize by very peculiar reaction pathways. For example, the cationic polymerization of lactams proceeds by activation of the monomer, as for their anionic polymerization ...
