Abstract

PURPOSE: To obtain a polyurethane elastomer having improved mechanical properties, with a high operating efficiency, by using a specific aromatic diamine as a curing agent.
CONSTITUTION: An aromatic diamine compound, e.g. 4, 4'-diamino-dichlorodibenzyl sulfide, of the formula (X is S or O; Y and Z are H or halogen), obtained by reducing a dinitro compound, formed from the corresponding nitrobenzyl halide and sodium sulfide, with iron powder, acetic acid, etc., as a curing agent is used for a reaction mixture of a polyisocyanate and a polyol or a prepolymer having terminal isocyanate groups. The equivalent ratio of the amino group in the agent or the amino group and the hydroxyl group in the polyol to the isocyanate group is preferably 0.8W1.2:1.
EFFECT: The low-melting agent provides greatly improved operating efficiency.
