摘要： A crosslinked polycarbonate is obtained by polycondensation of diol (A), trivalent or more polyhydric alcohol (B) whose arbitrary two hydroxy groups are not in the positional relationship of 1,2-disubstitution or 1,3-disubstitution, and carbonyl component (C) such as carbonic acid diesters. In the polycondensation step, no side reaction does not occur.This crosslinked polycarbonate is used as a modifier for polylactic acids. The brittleness of the polylactic acid is improved while maintaining mechanical strength, thermostability, and transparency.
