Biodegradable Block Copolymer Based on Polyether and Random Copolymers of Lactide and Caprolactone and There Application |
| abstract |
The present invention relates to a method for producing a polymer material having a new structure with biocompatibility and biodegradability used for medical applications, and more particularly, to a degradation of the decomposition rate and to a decrease in crystallinity during decomposition. It relates to a method for producing a block copolymer and its application. The biodegradable block copolymer according to the present invention is prepared by block copolymerization of a polyether and a random copolymer of caprolactone and lactide. As a result, the degradation properties of biodegradable block copolymers can be improved to delay the decomposition for several months to one year, and the degradation of crystallinity can be significantly reduced or eliminated in vivo. In addition to its large size, the mechanical properties are very excellent compared to conventional biodegradable block copolymers, and its value is also great for various medical materials. |
