A resin composition consisting essentially of (A) an aromatic polyester-polycarboxylic anhydride and (B) a polyamide. An article molded from the resin composition exhibits high heat resistance, mechanical properties and moldability. It is particularly resistant to cracking upon impact and is also resistant to breaking at a thin-walled portion.

Aromatic polyester

A resin composition consisting essentially of

Resin composition

An aromatic copolyester composition comprising (A) an aromatic copolyester derived from terephthalic acid, isophthalic acid and a bisphenol and (B) a phosphite compound, or an aromatic copolyester composition comprising components (A) and (B) plus (C) a metal salt of an organic carboxylic acid. Molded articles prepared from such aromatic copolyester compositions have superior mechanical properties and fire retardancy and reduced coloration and crazing.

Aromatic copolyester composition

A resin composition comprising (A) an aromatic copolyester comprising the reaction product in about equimolar amounts of (1) terephthalic acid and/or the functional derivatives thereof, isophthalic acid and/or the functional derivatives thereof and (2) a bisphenol and/or the functional derivatives thereof, (B) a polyamide, and (C) a polyalkylene phenylene ester or a polyalkylene phenylene ester ether, and a process for preparing the same. The resin composition has excellent moldability and the molded articles made therefrom have superior chemical resistance, thermal stability and mechanical properties.
