Resin composition

Abstract

Abstract PURPOSE:To provide a resin compsn. having excellent impact resistance, consisting of a polycarbonate resin and polymethylpentene. CONSTITUTION:A resin compsn. consists of 90-99pts.wt. polycarbonate resin (such as an arom. polycarbonate obtd. by using bisphenol A having an MW of 10.000- 100.000 as a main starting material) and 1-10pts.wt. polymethylpentene such as a polymer of 4-methylpentene-1 and pref. having melt flow characteristics close to those of the polycarbonate resin. This resin compsn. can be easily fabricated since impact resistance is greatly improved and melt viscosity is remarkably lowered. Further, the heat distortion temp. thereof is substantially the same as that of the polycarbonate resin. Thus, the resin compsn. can be used for applications requiring impact resistance without limitation to heat resistance.
