## Abstract Fibers of poly(lactic acid) (PLA) produced by twoβstep melt spinning have been studied. The PLA resins used contain a 96:04 ratio of L:D stereochemical centers; however, one of the materials is branched by a peroxide treatment. The thermal, mechanical, and morphological properties of th
## Abstract The higher order structure of stereocomplexβtype poly(lactic acid) meltβspun fibers of an equimolar blend of poly(Lβlactic acid) and poly(Dβlactic acid) was analyzed with wideβangle Xβray diffraction (WAXD) and birefringence measurements. Two different crystalline structures were observ
