STYRENE-BASED POLYMER COMPOSITION AND MOLDED PRODUCT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a molded product exhibiting chemical resistance especially even under a high strain, and to provide a styrene-based polymer composition effective as a molding compound for the molded product. SOLUTION: This styrene-based polymer composition is characterized by being obtained by compounding a total 100 pts.wt. blend of (A) a styrene-based polymer having an atactic structure or a blend of the styrene-based polymer having an atactic structure with a polyphenylene ether, (B) a styrene-based polymer having a syndiotactic structure and, if necessary, (C) a polyphenylene ether and (D) a rubber and/or a polyolefin where (B) component is contained by 3 to 90 pts.wt. to 100 pts.wt. total of (A)+(B)+(C)+(D), with (E) 0.05-10 pt(s).wt. plasticizer to 100 pts.wt. total of (A)+(B)+(C)+(D). The other objective molded product is obtained by molding the composition.
