Claim:
1. A modified polylactide (PLA) polymer comprising a biocompatible functional group (BFG) on a PLA polymer, wherein the BFG is at one or both ends of the polymer backbone or in the polymer backbone; wherein the modified polylactide polymer is according to one of the following formulae: wherein BFG1 and BFG2 are independently selected from the group consisting of —H, —CH wherein y is an integer ranging from 0 to 4 inclusive, and z is an integer ranging from 0 to 15 inclusive; BFG3 is selected from the group consisting of wherein p is an integer ranging from 0 to 3 inclusive, q is an integer ranging from 3 to 0 inclusive, provided p+q=3; and wherein the molecular weight of the polylactide polymer is from about 2,000 Daltons to about 2,000,000 Daltons.
