    • Disclosed are a polylactide stereocomplex with improved thermal stability and thus improved processability and a method for preparing the same. In order to confer flexibility to polymer chains, D-type polylactide polymer containing a small amount of caprolactone (poly D-lactide-caprolactone copolymer) is synthesized and it is uniformly mixed with L-type single-phase polylactide to prepare a flexible polylactide stereocomplex. Since the polylactide stereocomplex having flexible polymer chains has superior heat resistance and mechanical stability and experiences little decrease of the degree of stereocomplex formation even after thermal processing, the polylactide stereocomplex having improved thermal stability can be advantageously used for engineering plastics requiring high strength and good thermal stability, alternative materials for general-use plastics, high-performance medical materials, or the like because of its remarkably improved processability.
    • 公开了具有改进的热稳定性和因此改善的加工性的聚交酯立体络合物及其制备方法。 为了赋予聚合物链柔性,合成含有少量己内酯(聚D-丙交酯 - 己内酯共聚物)的D型聚丙交酯聚合物,并与L型单相聚丙烯酸酯均匀混合以制备柔性聚交酯立体络合物 。 由于具有柔性聚合物链的聚交酯立体络合物具有优异的耐热性和机械稳定性,并且即使在热加工后也几乎不降低立体复合物形成程度,所以具有改善的热稳定性的聚交酯立体络合物可有利地用于需要高强度和良好热的工程塑料 稳定性,一般用途塑料的替代材料,高性能医疗材料等,因为其显着改进的加工性能。

    • Disclosed is a method for manufacturing a polylactic acid composite composition, and a polylactic acid composite composition formed thereby. More particularly, there is disclosed a method for manufacturing a polylactic acid composite composition including: melting and blending a composition containing 60-80 wt % of a poly(L-lactic acid) resin, 15-30 wt % of a poly(D-lactic acid) resin and 5-10 wt % of a poly(ethylene-alkyl acrylate-glycidyl methacrylate) resin at 190-195° C.; and injecting the resulting melt in a mold whose surface temperature is 100-110° C. The present invention provides a material having superior heat resistance, impact strength and tensile strength by blending the PLLA resin, the PDLA resin and the poly(ethylene-alkyl acrylate-glycidyl methacrylate) resin at specific proportion, under controlled processing and molding conditions. The polylactic acid composite composition prepared according to the present invention can replace the petroleum-based general-use polymer resins and engineering plastic materials that have been used for automobile parts with the environment-friendly biomass-based biomaterials, and may be usefully utilized for automobile interior and exterior parts.
