Abstract

PURPOSE: To obtain a high-quality polycarbonate-polyol in high yields, by transesterifying a specified amount of a dialkyl or diaryl carbonate with a specified amount of a polyhydroxy compound in the presence of a specified amount of a titanium catalyst.
CONSTITUTION: The production of a polycarbonate-polyol by reacting a dialkyl carbonate or diaryl carbonate with a polyhydroxy compound in the presence of a titanium catalyst is performed with a ratio of said polyhydroxyl compound to said dialkyl carbonate or said diaryl carbonate being 1.0W1.30 times as high as the stoichiometric one in the presence of 0.0005W0.05wt.%, based on said dialkyl carbonate or said diaryl carbonate, said titanium catalyst. By reacting the polyacrbonate-polyol thus produced with a diisocyanate, a polyurethane resin markedly excellent in wet heat resistance and hydrolysis resistance can be obtained.
