Patent

CA 2170941

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-~, II ~O-R5-C(O)-~, and III ([-O-R5-C(O)]P-O-)L G XI and combinations thereof.
