Optically active block copolymerized polyester and method for producing the same |
| abstract |
(57) [Summary] [Structure] An optically active β-butyrolactone and a lactone other than the optically active β-butyrolactone are successively subjected to ring-opening copolymerization in the presence of a catalyst. The following general formulas (I) and (II): (In the formula, * represents an asymmetric carbon atom, and m and n each represent a natural number from 300 to 5000.) An optically active block copolymerized polyester comprising a structural unit represented by the formula. [Effect] It becomes a high-strength biodegradable and hydrolyzable material having a high molecular weight and a high melting point (130 ° C. or higher) that can be practically used. |
