POLYCARBONATE RESIN COMPOSITION FOR GAS ASSIST INJECTION MOLDING PROCESS FOR PRODUCING BLOW-MOLDED ARTICLE AND BLOW-MOLDED ARTICLE

摘要

In particular, a molded article having a relatively high hollow ratio mainly composed of a polycarbonate resin, particularly a molded article having a rib structure, is excellent in uniformity in thickness of a molded article and easy to form ribs, and a polycarbonate-To a resin composition.;The present invention relates to a polycarbonate resin composition comprising a polycarbonate resin composition comprising (A) 30 to 100% by weight of a polycarbonate resin and (B) 70 to 0% by weight of a styrene resin, wherein a shear rate of 10^-One(Pa sec) and shear rate 1000 (sec^-One(H / L) of a melt viscosity L (Pa sec) measured at a temperature of 100C. or higher in a molten state of a polycarbonate resin composition for gas injection injection molding having a melt viscosity ratio H / L of 5 or more. The present invention also relates to a production method for producing a hollow molded article by gas injection injection molding using the polycarbonate resin composition and expanding the volume of the mold cavity under pressure of gas injection. Further, the present invention provides a molded article produced by the gas injection injection molding method using the above polycarbonate resin composition.
