    摘要： A polycarbonate/polyethylene terephthalate composite resin composition is provided, which contains a resin component of 100 parts by weight and contains a phosphorus thermal stabilizer of 0.01 to 0.5 parts by weight and/or a hindered phenol thermal stabilizer of 0.01 to 1 parts by weight, the resin component containing a polycarbonate resin of 95 to 30 weight % and a polyethylene terephthalate resin of 5 to 70 weight %. The polyethylene terephthalate resin contains a deactivated polycondensation catalyst. The polycarbonate/polyethylene terephthalate composite resin composition can be prevented from being deteriorated resulting from being thermally preserved.
