NOVEL BRANCHED OXETANE POLYESTER

摘要

A novel branched oxetane polyester having one or more oxetane groups is disclosed. Said branched oxetane polyester is the reaction product of at least one di, tri or polyhydric compound, at least one di, tri or polycarboxylic acid or an analogous alkyl ester, halide or anhydride, and at least one compound having at least one oxetane group and at least one hydroxyl group. Said di, tri or polyhydric compound works as an initiator, core or nucleus, from which at least two branches, built up from said di, tri or polycarboxylic acid or said analogous alkyl ester, halide or anhydride and said compound having said at least one oxetane group and said at least hydroxyl group, radiates.
