Title:
POLYOL AND URETHANE RESIN USING THE SAME
Document Type and Number:
Japanese Patent JP3550976
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a polyol good in workability and curability, and capable of giving a cured product of high crosslink density and excellent solvent resistance, chemical resistance and coating film properties, by reaction of a specific triol with a specific lactone or cyclic ether.
SOLUTION: This polyol is obtained by reaction of (A) a triol of formula I (R1 to R3 are each an alkyl or the like) (e.g. 3-hydroxymethyl-1,6-hexanediol) with (B) a lactone of formula II (R4 is a cycloalkyl or the like; (n) is 1-6) (e.g. ε-caprolactone) or (C) a cyclic ether of formula III (R5 is an alkyl or the like; (n) is 0-7) (e.g. ethylene oxide). The other objective polyurethane resin is obtained by reaction of the above polyol with a polyisocyanate compound pref. at 10-100°C.
