Abstract

Copolyesters from ε- caprolactone and 2,2-dimethyl-1,3-propanediol have been synthesized by using distannoxane as catalyst. The influence of monomer compositions on viscosity, melting point and structure of polyesters was studied. The results showed that the increase of ε- caprolactone content in copolymer increased the melting point and viscosity of polyester. This was supported by the decrease of hydroxyl number of polyester when the ε- caprolactone monomers in the copolymers increased.
