Method of preparing a physically cross-linked, lactide-based polymer system, polymer system prepared by the method, and process of manufacturing an object from the polymer system.

摘要

The invention provides a method of preparing a lactide-based, biodegradable (biocompatible), physically cross-linked and highly elastic polymer system. The method comprises the steps of: preparing a melt of a copolymer based on a first comonomer and at least one second comonomer, the first comonomer being selected from L-lactide and D-lactide; and adding a lactide-containing stereocomplex forming agent to the melt, wherein the stereocomplex forming agent is selected such that the resulting polymer system comprises a combination of constitution units derived from L-lactide and constitution units derived from D-lactide forming stereocomplexes.
