Fund Project:

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.
