PURPOSE:To obtain the titled resin composition exhibiting high heat deformation temperature even under high load and having excellent thermal stability, impact resistance, processability and luster, by compounding a polyamide resin with an aromatic vinyl resin component copolymerized with an imide compound of an alpha,beta-unsaturated dicarboxylic acid. CONSTITUTION:The objective composition is produced by compounding 50-95wt.% especially 60-80% polyamide resin with 5-50%, especially 20-40% aromatic vinyl resin copolymerized with an imide compound of an alpha,beta-unsaturated dicarboxylic acid. The aromatic vinyl resin is selected from (A) a copolymer of (A1) 70-99.9% monomera consisting of (a1) 20-80% aromatic vinyl compound, (a2) 20-80% imide compound of an unsaturated dicarboxylic acid and (a3) 0-60% copolymerizable vinyl compound and (A2) 0.1-30% monomer containing a functional group, (B) a copolymer produced by the graft copolymerization of the monomers of the polymer A in the presence of a non- conjugated diene rubber polymer, (C) a mixture of the polymers A and B, (D) a mixture of the polymer A and a non-conjugated diene rubber polymer modified with a monomer having a functional group and (E) a mixture of the polymers B and D. |
