Patent ID: 10619004

Abstract:
It is possible to enhance flowability of a polycarbonate resin during molding of the polycarbonate resin without impairment of inherent properties of the polycarbonate resin by blending a flowability enhancing agent and an antioxidant with the polycarbonate resin, the flowability enhancing agent including polyester which is a polycondensate of a monomer mixture, the monomer mixture being a mixture of monomers (A), (B), and (C), which are biphenol (A), bisphenol (B), and dicarboxylic acid (C), respectively, the monomer mixture containing the biphenol (A) in an amount of 0 mol % to 55 mol %, the bisphenol (B) in an amount of 5 mol % to 60 mol %, and the dicarboxylic acid (C) in an amount of 40 mol % to 60 mol %, with respect to 100 mol % of a total amount of the monomers (A), (B), and (C), and the polyester having terminals 60% or more of which are sealed with a terminal sealing agent having a number average molecular weight of not less than 160.
