IMPACT-RESISTANT THERMOPLASTIC POLYSTYRENE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain a highly weather-resistant, highly impact-resistant thermoplastic polystyrene resin composition reinforced by a partially or completely crosslinked unsaturated rubber polymer. SOLUTION: This impact-resistant thermoplastic polystyrene resin composition comprises at least (A) from 60 to 99 pts.wt. polystyrene resin, (B) from 1 to 40 pts.wt. partially or completely crosslined unsaturated rubber polymer and (C)<50 pts.wt. compatibilizer against 100 pts.wt. total of components (A) and (B).
