Abstract

PURPOSE:To obtain a molded product which is excellent in heat resistance and elongation characteristics, by using a specified diaminobenzene derivative as a chain extender in the reaction injection molding of a high-MW active hydrogen compd. and a polyisocyanate. CONSTITUTION:A chain extender is prepared, which comprises of diaminobenzene derivative (e.g., 3,5-diamino-4-methyl-nitrobenzene) having an electrophilic group selected from among a halogen atom., a nitro group, a trihalomethyl group, a cyano group, an alkoxycarbonyl group, an N-alkyl-substd. carbamoyl group and an alkoxysulfonyl group and further having, if necessary, an alkyl group. A starting material comprising said chain extender, a high-MW active hydrogen compd. and optionally added another chain extender, catalyst, foaming agent, etc. and another starting material comprising a polyisocyanate compd. (e.g., tolylene diisocyanate) are submitted to reaction injection molding to give a synthetic resin molding.
