| titleOfInvention | Biodegradable optically active polymer and method for producing the same |
| abstract | (57) [Summary] [Structure] The following general formula (II): (In the formula, R 1 represents a hydrogen atom or an alkyl group having 1 to 5 carbon atoms) and at least one lactide selected from compounds represented by the general formula (III): (In the formula, R represents an alkyl group having 1 to 5 carbon atoms.) Optically active 7-substituted-1,4-dioxepane-5 General formula (I) obtained by ring-opening copolymerization of -one with (In the formula, R and R 1 have the same meanings as described above, and m and n represent natural numbers.) And the ring-opening in the presence of at least one catalyst selected from organotin compounds. A method for producing a polymer represented by the above general formula (I), in which copolymerization is carried out. [Effect] A novel optically active, enzymatically degradable and hydrolyzable copolymer can be produced by an industrially advantageous method. |
