PRODUCTION METHOD OF TRANSPARENT RESIN COMPOSITION INCLUDING POLYCARBONATE RESIN AND ACRYLIC RESIN

摘要

PROBLEM TO BE SOLVED: To provide a production method of a transparent resin composition including a polycarbonate resin and an acrylic resin where the polycarbonate resin and the acrylic resin are continuously kneaded and the transparent resin composition can be obtained.SOLUTION: In a production method of a transparent resin composition, a molten mixture resin C is produced by continuously supplying a polycarbonate resin A and an acrylic resin B to a twin screw extruder 13, subsequently, the molten mixture resin C is supplied to a monopodial extruder 15 having a screw 42 for kneading provided with a shear processing part 43, and the transparent resin composition D is obtained by kneading the molten mixture resin C with the shear processing part 43 rotating at 500 rpm or more and 4,000 rpm or less.
