Zusammenfassung:PURPOSE:To improve heat resistance, mechanical characteristics, solid phase adhesion, and weatherability by compounding a PP resin, a styrenic resin, a compatibilizer, a benzotriazole compd., a hindered amine compd., and a resorcinol monobenzoate. CONSTITUTION:100 pts.wt. in total of a PP resin (A) having an MI of 5-60g/10min and a styrenic resin (B) having an MI of 0.5-20g/10min is compounded with 10-30 pts.wt. compatibilizer (C) in a wt. ratio of (B+C) to (A+B+C) of 0.2-0.6 to give a compsn. Then, the compsn. is compounded with 0.05-0.9 pt.wt. benzotriaziole compd. [e.g. 2-(2'-hydroxy-5'-methylphenyl) benzotriazole], 0.05-0.9 pt.wt. hindered amine compd. [e.g. di-(2,2,6,6-tetramethyl-4- piperidyl) sebacate], and 0.05-0.9 pt.wt. resorcinol monobenzoate, each based on 100 pts.wt. resins A and B.
