RUBBER-MODIFIED STYRENIC RESIN COMPOSITION AND ITS INJECTION BLOW MOLDED ITEM

摘要

PROBLEM TO BE SOLVED: To provide a rubber-modified styrenic resin composition for injection blow molding which very hardly allows black-dot foreign matters to occur in a molded article when a molding machine is restarted after its stop and which is excellent in mold releasability and moldability in continuous molding; and its injection blow molded item. SOLUTION: This rubber-modified styrenic resin composition is prepared by adding (b) 0.006-0.5 pt.wt. phenolic thermal degradation inhibitor and 0.02-0.5 pt.wt. sum of (c) a higher fatty acid metal salt and (d) a higher fatty acid to (a) 100 pts.wt. rubber-modified styrenic resin containing rubbery polymer particles dispersed therein.
