POLYCARBONATE STRYRENE BASED COPOLYMER ALLOY COMPOSITION AND INJECTION MOLDING

摘要

The present invention relates to a polycarbonate styrene copolymer alloy composition and a molded product thereof. According to the present invention, a lamella filler-pigment mixture as a pigment for an alloy of a polycarbonate resin and a styrene copolymer, and a potassium silicate-dye mixture (i.e. marble pigment) as a pigment for providing a spot marble pattern after injection molding are used to ensure mechanical strength, dimensional stability after molding, workability, post-processability and surface gloss, which are required to the polycarbonate styrene-based copolymer alloy composition and also provide the spot marble color under improved whiteness. Also, the molded product obtained from the polycarbonate styrene copolymer alloy composition may be provided.
