Abstract: A solid-phase polymerization method of high-molecular-weight aliphatic polyester conducts the solid-phase polymerization of aliphatic polyester prepolymer under a gas stream containing sulfonic acid catalyst. The method features preparing metal free aliphatic polyester with high molecular weight, good color and luster and perfect thermal stability efficiently. The non-metal-ion aliphatic polyester is not only applicable to common use, but is also suitable as high value-added medical material and packing material which contacts with food directly than other metal-containing polyester.
