Abstract

A polymerization process to derive a thermal-stabilized poly(1,4-dioxan-2-one) and cyclic ester monomer copolymer using a coordination-insertion catalyst/initiator. 1,4-dioxan-2-one and cyclic ester monomer, each containing less than 100-ppm water and having an acid value less than 0.5 mg KOH/g, and preferably less than 0.2 mg KOH/g, are copolymerized. Preferably the cyclic ester monomer is e-caprolactone and the reaction is in an extruder.
