Abstract: A process for producing a polycarbonate polyol by ester-interchange reaction of a dialkyl, diaryl or alkylene carbonate and a polyhydroxy compound, wherein the dialkyl, diaryl or alkylene carbonate is purified by adsorption treatment with an adsorbent prior to use in the reaction. A process for producing a polycarbonate polyol which comprises ester-interchange reaction of a dialkyl or diaryl carbonate and a polyhydroxy compound in the presence of a catalyst, wherein the proportion of the polyhydroxy compound to the dialkyl or diaryl carbonate is 1.01 to 1.30 times its stoichiometrical amount, and the amount of the catalyst is 0.0001 to 0.5% by weight, calculated as metal, based on the dialkyl or diaryl carbonate. Also provided is a process for producing a polycarbonate polyol by ester-interchange reaction of a dialkyl, diaryl or alkylene carbonate and a polyhydroxy compound in the presence of a catalyst in an amount, as metal, of 0.0001 to 0.

Abstract: A resin composition curable at room temperature and useful, for example, as a coating agent, an adhesive and a sealing agent. The composition consists essentially of (A) a polymer having both carboxyl and tertiary amino groups, the polymer being the reaction product of (a-1) a vinyl polymer having both carboxylic anhydride and carboxyl groups with (a-2) a compound having both at least one group containing an active hydrogen capable of reacting with the carboxylic anhydride group in the polymer (a-1) and at least one tertiary amino group, and (B) a polyepoxy compound.
