## Abstract The crystal modifications and multiple melting behavior of poly(Lβlactic acidβ__co__βDβlactic acid) (98/2) as a function of crystallization temperature were studied by wideβangle Xβray diffraction (WAXD) and differential scanning calorimetry (DSC). It was found that the disorder (Ξ±β²) an

## Abstract This article contains a detailed calorimetric analysis of the multiple melting behavior of poly(Lβlactic acid) (PLLA) in dependence of crystallization conditions. PLLA crystals formed upon primary crystallization have a greater tendency to reorganize into more stable structures during t
## Abstract **Summary:** The use of hyperbranched polymers (HBP) with hydroxy functionality as modifiers for poly(Lβlactic acid) (PLLA)βflax fiber composites is presented. HBP concentrations were varied from 0 to 50% v/v and the static and dynamic tensile properties were investigated along with int
