摘要
The present invention relates to methods for preparing biodegradable polymer stereocomplexes using a supercritical fluid-organic solvent system and polymer stereocomplexes prepared by such methods. The method of the present invention involves introducing two types of homopolymers having different stereostructures and a small amount of organic solvent into a reactor, adding a supercritical fluid thereto, followed by applying a specific temperature and pressure to form a polymer stereocomplex having a crystalline structure. According to the method of the present invention, biodegradable polymer stereocomplexes in the form of powder or porous foam having excellent thermal and mechanical stabilities can be prepared in a simple, economical and environmentally-friendly manner in a single process.
