<P>PROBLEM TO BE SOLVED: To obtain a bioabsorbable polymer which is composed of a lactide and ε-caprolactone and in which self-curing is hardly progressed. <P>SOLUTION: Self-curing is suppressed by making the molar ratio of the lactide to the ε-caprolactone within a range from 80/20 to 20/80, and making the average chain lengths of the lactide and ε-caprolactone to 4.0 or shorter, respectively. In a preferred embodiment in which particularly the self-curing is hardly progressed, the average chain length of the lactide is 3.55 or shorter and 2.31 or longer, and/or the average chain length of the ε-caprolactone is 3.81 or shorter and 2.71 or longer. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
