Abstract:
The present invention relates to a polymer obtainable by reaction of a polyester comprising a quantity of carboxylic terminal groups with a chain extending compound wherein the chain extending compound is selected from an aromatic bis(oxirane ether) or an aromatic bis(methyloxirane ether). Such polymer may have a desired resistance to hydrolytic degradation.
