Ring Opening Template Copolymerization

Ring-opening copolymerization was simultaneously investigated with homopolymerization of N-carboxy-a-amino acid anhydrides, NCAs, by Bamford at al Polymerization of a mixture of NCAs of y-ethyl-L-glutamate and sarcosine  

Copolymerization of similar monomers was investigated by Volpe and Frisch. The effect of poly(2-vinylpyridine) on the copolymerization of L-AlaNCA

There is far less information in the scientific literature about template copolymerization than about template homopolymerization. As in the case of template homopolymerization, template copolymerization can be realized according to different types of reaction stepwise (template polycondensation), copolyaddition, radical or ionic polymerization, ring-opening copolymerization, etc. 

Copolymerization can be conducted stepwise (template copolycondensation), copolyaddition, radical or ionic copolymerization, ring-opening copolymerization, etc. 

In principle, template copolymerization can be realized according to different reaction types as template copolycondensation, template copolyaddition, ring-opening copolymerization, and radical or ionic copolymerization. However, radical template copolymerization is slightly more elaborated. The process of template copolymerization can be classified from the point of view of stmcture of the template. We can make a distinction between two cases whether the template is a homopolymer or a copolymer. An important role in the process of template copolymerization plays a difference in interactions between the template and two comonomers.
