The present invention describes an aliphatic polyoxaamide polymer and blends thereof that may be used to produce surgical devices such as sutures, sutures with attached needles, molded devices, and the like. The aliphatic polyoxaamide of the present invention have a first divalent repeating unit of formula I: [X-C(O)-C(R1)(R2)-O-(R3)-O-C(R1)(R2)-C(O)-]Iand a second repeating unit selected from the group of formulas consisting of: [-Y-R17-]T,I [-O-R5-C(O)-]B, andII ([-O-R9-C(O)]P-O-)LGXIand combinations thereof, wherein X and Y are selected from the group consisting of -O- and -N(R)-, provided both X and Y are not both -O- and may be blended with a second polymer that is preferably biocompatable.
