Claim:
1. A polymeric material comprising a plurality of biodegradable polymers having a polydispersity or molecular weight distribution from about 1.5 to about 2.5, wherein the plurality of biodegradable polymers comprises a first polymer in an amount from about 5% to about 15%, a second polymer in an amount from about 15% to about 25%, a third polymer in an amount from about 45% to about 55%, and a fourth polymer in an amount from about 15% to about 25% by weight, and the first polymer comprises 100% poly(D,L-lactide) having ester end groups, the second polymer comprises 100% poly(D,L-lactide) having carboxylic acid end groups, the third polymer comprises 100% poly(D,L-lactide) having ester groups and the fourth polymer comprises 100% poly(D,L-lactide having ester groups.
