Bioabsorbable polymer and process for preparing the same

摘要

A bioabsorbable, ternary block copolymer consisting essentially of (A) polylactic acid segment, (B) poly( epsilon -caprolactone) segment and (C) polyglycolic acid segment, preparation process of the block copolymer, and medical molded articles prepared from said block copolymer. The bioabsorbable block copolymer is excellent in mechanical strength and flexibility and has moderate hydrolyzability and is especially utilized for a surgical monofilament suture.
