Abstract:
1. A polymer composition comprising: a first lactic acid polymer which comprises at least three chains of lactic acid units attached to a polyfunctional initiator residue, at least a segment of each chain being in the R- or the S-configuration; and a second lactic acid polymer which is linear and contains at least a segment which has a steric configuration opposite to the steric configuration of the lactic acid polymer chains of the first polymer, wherein the composition has a single melting temperature, and wherein the composition comprises from about 15 weight parts to about 30 weight parts of the first lactic acid polymer and from about 70 weight parts to about 85 weight parts of the second lactic acid polymer, wherein the first lactic acid polymer and the second lactic acid polymer total 100 weight parts.
