PURPOSE: To provide the titled molding material with excellent electric properties, chemical resistance, impact resistance and heat resistance using a resin obtained by reacting a reaction product of a diamine and a specific dicarboxylic acid anhydride with a multifunctional carboxylic acid compound.

CONSTITUTION: To 100pts.wt, of (A) a reaction product with m.p. of 150°C or less obtained by reacting 1mol of (a) a diamine (reactive derivative) such as m-phenylenediamine and 0.05W0.6mol of (b) a dicarboxylic acid anhydride having an ethylenic C-C double bond such as maleic anhydride under a molten condition at 90W200°C for 10W60min, 10W60pts.wt. of (B) a multifunctional carboxylic acid compound such as terephthalic acid is compounded and kneaded at 50W120°C for 5W30min to obtain a resin (C). Subsequently, to 100pts.wt. of this resin (C), 5W 20pts.wt. of novolac resin (D) and a curing accelerator are added and the obtained mixture is kneaded at room temp.W120°C to obtain the titled molding material.
