Synthesis and Properties of Unsaturated Polyesters with Acryl Skeletons on their Backbone

Abstract

Poly（ conjugates ester） s（ PCEs） are unsaturated polyesters containing acryloyl skeletons on their back bone. PCEs can prepared by polycondensation of acrylates bearing two reactive groups and ring-opening po lymerization（ ROP） of cyclic acrylates. PCEs are photo- and thermo-curable and capable of quantitative post polymerization modification by thiol-ene reaction, and some of them undergoes chemoselective main-chain scission by conjugate substitution reaction. Therefore, PCEs are promising reactive polymers, and recent studies on PCEs have referred a potential as a precursor of bio-degradable polyesters. In this review, I report synthesis, properties and some application examples of PCEs.
