A polymer with a copoly(ether‐ester‐amidic) structure. I. Synthesis and preliminary physico‐chemical characterization

Abstract

A procedure is described for the preparation of a block copolymer with A‐B‐A sequences in which ω‐ω′‐dihydroxy‐poly‐(ethylene glycol) is inserted between two polymeric monoacidic chains of polycaproamide and bonded to them by means of ester links. The resulting material was characterized. The copolymer is isomorphous with the polycaproamide. Thermal treatments induce a crystalline transition γ → α as in polycaproamide. The influence of the moisture content on the glass transition temperature and on the storage modulus is discussed.
