摘要: 以等比例的聚L乳酸（PLLA）和聚D乳酸（PDLA）树脂为原料，先通过低温共混制备聚乳酸全立构粉末，然后将立构粉末与成核剂、玻璃纤维等混合，直接在注塑机中成型，注塑样品经热处理后，得到高耐热性能聚乳酸（PLA）样品，经测试，其维卡软化温度高达165℃以上，差示扫描量热分析（DSC）结果表明，处理后的样品富含立构物结晶，立构物结晶熔融焓高达27.6 J/g。拉伸强度较纯PLA也有大幅提升，达到129 MPa。

Abstract: The stereocomplex powder was prepared by mixing the same amount of poly(L-lactide)(PLLA) and poly(D-lactide)(PDLA) resins at a relative low temperature and then was mixed with the nucleation agent and glass fiber. The mixture was molded in the injection machine, followed by annealing at different temperatures to form the blends with high heat resistance. The vicat softening temperature reached to 165℃ and the DSC results revealed that the blends were rich in stereocomplex and the enthalpy was as high as 27.6 J/g. Moreover, the tensile strength was increased greatly to 129 MPa.
