FLAME RETARDANT STYRENE-BASED RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain a styrene-based resin composition excellent in heat resis tance and having high flame retardance. SOLUTION: This flame retardant styrene-based resin composition is characterized in that the resin composition comprises (A) a rubber-modified styrene-based resin (component A) having 0.20-1.50 dL/g reduced viscosity and (B) an orgnophosphorus compound containing at least 30 wt.% of a specific cyclic phosphoric ester compound (component B) and the amount of the component B is 1-70 pts.wt. based on 100 pts.wt. of the component A.
