Photosensitive polymeric esters produced by the condensation of a chloromethyl groups-containing polymer with a carboxyl salt

摘要

Production of a polymeric ester having photosensitive properties and the following group in the side chain of its repeating unit WHEREIN R is an aliphatic chain, R1 is hydrogen or a nitrile group, R2 is a substituted or non-substituted aromatic group and a and b are 0 or 1. The ester can be prepared by reacting polyglycidol or a polyacrylate with an acid halide or by condensing a polymer with a chloromethyl group in its aliphatic side chain with a carboxyl salt.
