## Abstract Poly(lactic acid) (PLA) was blended with five plasticizers in a batchwise mixer and pressed into films. The films were analyzed by means of dynamic mechanical analysis and differential scanning calorimetry to investigate the properties of the blends. Triacetine and tributyl citrate prov
The zone-drawing (ZD) method was applied three times to the melt-spun poly(L-lactic acid) (PLLA) fibers of low molecular weight (M v Ο 13,100) at different temperatures under various tensions. The mechanical properties and superstructure of the ZD fibers were investigated. The resulting ZD-3 fiber h
