Quaternary ammonium salts of α-pyrrolidone, α-piperidone and e-caprolactam, prepared extra situ, were used as catalysts in anionic polymerization of these lactams. Pyrrolidone and piperidone salts gave the corresponding lactam polymers of increased

A new synthesis of poly(L-cystyl-L-cystine) by using N,N'-bis(trimethylsilyl)cystine dibenzyl ester is described. The polycondensation of the latter with N,N'-bis(benzyloxycarbonyl)cystine bis(pentafluorophenyl) ester allowed us to obtain polymers ha

In this paper, we study the photoinduced polymerization of bisimide models for our new soluble side-chain-substituted negative-type photosensitive polyimides (PSPI) in order to better understand the polymerization behavior of the latter. These model

Polyisopeptides are non-peptidic polymers formed by α,ω-polycondensation of tri- or multi-functional α-amino acids. They are expected to possess physical and mechanical properties of synthetic polyamides (or polyesters) and to be biodegradable. In
