PURPOSE:A composition that contains polyarylate, polyamide and a polymer containing N-substituted amides, thus showing increased compatibility and mechanical properties without any adverse effect on good moldability and oil resistance that are merits of polyarylate/polyamide composition. CONSTITUTION:The objective composition comprises (A) 100pts.wt. of an aromatic polyester copolymer that is obtained from a mixture of terephthalic acid and isophthalic acid or their functional derivatives (in which the molar ratio of terephthalic acid to isophthalic acid is 9/1-1/9) and 2,2-bis(4'-hydroxyphenyl)propane, (B) 10-150pts.wt. of polyamide and (C) 3-50pts.wt. of a copolymer containing N-substituted amides. Polyhexamethylene-adipamide or polycaprolactam is preferred as component B. Component C is, e.g., piperazine, sym-dialkylalkylenediamine or the like and its polymerization degree is preferably 10-200. |
