POLYSTYRENE RESIN COMPOSITION WITH CHEMICAL RESISTANCE AND MOLDING THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a resin composition giving polystyrene resin moldings with excellent chemical resistance having excellent physical properties. SOLUTION: This polystyrene resin composition with chemical resistance comprises 10 to 95 pts.wt. of (A) a styrene polymer having atactic structure or a styrene polymer having atactic structure and polyphenylene ether in total amounts, and 90 to 5 pts.wt. of a styrene polymer having syndiotactic structure of which the peak value of the crystallization temperature (Tc) is 220 deg.C or lower when cooled from 300 deg.C at a cooling rate of 20 deg.C/min by the differential scanning calorimeter(DSC).
