ABSTRACT:
A curable composition includes an unsaturated polyester and an unsaturated monomer copolymerisable with the unsaturated polyester in the presence of polymerisation accelerators and initiators. The unsaturated polyester is an epoxidised unsaturated polyester obtainable by reaction between unsaturated polyester obtainable by reaction between the carboxy end groups of a polyester having unsaturated monomer units and the epoxy groups of an epoxy resin.
