POLYOL COMPOSITION, PROCESS FOR PRODUCING THE SAME AND PROCESS FOR PRODUCING POLYURETHANE USING THE POLYOL COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a polyol composition which has a lower viscosity than the conventional ones and is easy to handle, a process for producing the same and a process for producing a polyurethane using the polyol composition.

SOLUTION: The polyol composition is obtained by subjecting a polycarboxylic acid having three or more carboxyl groups in the molecule, a hydroxycarboxylic acid having a hydroxyl group and one or two carboxyl groups in the molecule and an active hydrogen compound having at least two active hydrogens in the molecule to a dehydration condensation reaction.
