LIGHT-RESISTANT RUBBER-REINFORCED STYRENIC RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To improve the light resistance of a dienic rubber-reinforced styrenic resin. SOLUTION: This light-resistant rubber-reinforced styrenic resin composition comprises (A) 100 pts.wt. of a dienic rubber-reinforced styrenic resin, (B) 4-20 pts.wt. of a coloring agent (limiting only to alumina-treated titanium dioxide, when titanium dioxide is used), and (C) 0.4-5 pts.wt. of a hindered amine and (or) a UV light absorbent.
