Abstract
Disclosed herein is a process for producing polyurethane moldings having good physical properties and good receptivity of electrostatic coating, said process comprising reacting a polyoxyethylene chain-containing polyether polyol having 2-4 hydroxyl groups and a hydroxyl equivalent higher than 750 as the high-molecular weight polyol, diaminotoluene and a low-molecular weight polyol having a hydroxyl equivalent of 30-100 as the low-molecular weight, active hydrogen-containing compound, with organic polyisocyanates in specific equivalent ratios respectively. The process may advantageously applied to injection reaction molding.
