Crystal density and heat of fusion for a stereo-complex of poly(L-lactic acid) and poly(D-lactic acid)

Measured densities of films, consisting of only stereo-complex (sc) crystals of poly(l-lactic acid) (PLLA) and poly(d-lactic acid) (PDLA), are sometimes significantly higher than the density of the sc-crystal calculated on the basis of the previously proposed triclinic and trigonal unit cells. In th...
