| titleOfInvention | Biodegradable copolymer, a biodegradable polymer composition, a biodegradable article, and a preparation process thereof |
| abstract | Disclosed are a biodegradable copolymer and a biodegradable article molded therefrom, said copolymer having a number average molecular weight ranging from 1,000 to 1,000,000 consisting essentially of (A) from 5 to 99% by mol of epsilon-caprolactone or delta-valerolactone structural units and (B) from 95 to 1% by mol of oxetane structural units, said structural units being combined in the state of a block, and containing an organic aluminum-based Lewis acid represented by general formula (I) <IMAGE> (I) wherein R is an alkyl group having a carbon number ranging from 1 to 4, Y is independently selected from a substituted group, and p is any one of 1, 2 and 3. Also disclosed are block polymers of lactone and dimethyltrimethylene carbonate and blends of polylactone with polyoxetane. |
