Abstract
Abstract A polymeric material which is superior in mechanical strength, dimensional stability, moldability and resistances to chemicals, heat and abrasion comprises a copolymer composed of polymer chain moieties of a copolymer containing an imide compound of an a,p-unsaturated dicarboxylic acid and polymer chain moieties of a polyamide, both chain moieties being bonded to each other. The material may be blended with thermoplastic resins. Furthermore, the material may be reinforced with glass fiber, etc.
