SOLVENT-RESISTANT STYRENE RESIN COMPOSITION AND EXPANSION MOLDED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a styrene resin composition showing an improved solvent resistance which realizes cost reduction, and an expansion molded product. SOLUTION: The solvent-resistant styrene resin composition contains (A) 97-40 wt.% styrene polymer having an atactic structure and (B) 3-60 wt.% styrene polymer having a syndiotactic structure and shows a relative degree of crystallinity of <30%. The expansion molded product obtained by expansion molding the composition shows the high solvent-resistance and realizes cost reduction through reduction in weight which is preferably reduced by 3-80 wt.%.
