<p>The present invention describes a new aliphatic polyoxaesters that is bioabsorbable and may be used to produce surgical devices such as sutures, sutures with attached needles, molded devices, and the like. The invention also contemplates a process for producing these polyesters. The aliphatic polyoxaesters of the present invention have a first divalent repeating unit of formula I: ¢O-C(O)-C(R1)(R2)-O-(R3)-O-C(R1)(R2)-C(O)-! I and a second repeating unit selected from the group of formulas consisting of: ¢-O-R4-!A, II (¢-O-R5-C(O)-!B, and III (¢-O-R5-C(O)!p-O-)LG XI and combinations thereof.</p> |
