POLYCARBONATE-HYDROGENATED POLYBUTADIENE COPOLYMER, METHOD FOR PRODUCING SAME, AND POLYCARBONATE RESIN COMPOSITION USING SAME

摘要

Disclosed is a polycarbonate-hydrogenated polybutadiene copolymer containing repeating units (I) and (II) having specific structures. Also disclosed is a polycarbonate resin composition obtained by melt-mixing a blend which is obtained by blending the polycarbonate-hydrogenated polybutadiene copolymer (iii) into a mixture of 45-99% by mass of a polycarbonate resin (i) and 55-1% by mass of a polyolefin resin (ii) in an amount of 0.1-30 parts by mass per 100 parts by mass of the resin mixture. The polycarbonate resin composition is improved in compatibility between the polycarbonate resin and the polyolefin resin, while having impact resistance, fluidity and chemical resistance without suffering from lamellar separation.
