Interaction of polyesters with epoxy polymers: Insertion of oxirane rings into ester bonds
Abstract Epoxy oligomers readily interact (hardening) with polyesters of different structures (heterochain, carbochain, aliphatic, aromatic), as indicated by the change of properties and infrared spectra of an epoxy polymer–polyester composition on heating. The curing is caused by the reaction of th...

Abstract Epoxy oligomers readily interact (hardening) with polyesters of different structures (heterochain, carbochain, aliphatic, aromatic), as indicated by the change of properties and infrared spectra of an epoxy polymer–polyester composition on heating.
