Patent ID: 7862830

Claim:
A composition, comprising: from about 50 wt % to about 99 wt % of a first single enantiomer homopolymer, wherein the first single enantiomer homopolymer is poly(L-lactide); from about 1% to about 50% of a stereocomplex of a 1:1 blend of a second single enantiomer homopolymer, wherein the enantiomer for the blend is poly(D-lactide), which may have the same or a different chemical composition as the first single enantiomer homopolymer, with a homopolymer of a mirror-image enantiomer of the second single enantiomer homopolymer; wherein: the molecular weight of the first single enantiomer homopolymer is sufficiently higher than the molecular weight of each of the second single enantiomer homopolymer and its mirror-image enantiomer homopolymer such that the first single enantiomer homopolymer forms a continuous phase of the composition and the stereocomplex blend forms a discrete phase of the composition.
