Document Type and Number:
WIPO Patent Application WO/2014/007366
Kind Code:
A1
Abstract:
A modified polyalkylene oxide which is obtained by reacting a polyalkylene oxide compound (A), a polyether monoalcohol (B) and a diisocyanate compound (C). The compound (A) is a polyethylene oxide represented by formula (II).
HO-(CH2CH2O)n-H (II)
(In formula (II), n represents an integer of 130-680.)
The compound (B) is a polyether monoalcohol which has a structure wherein one end of a random copolymer of ethylene oxide and propylene oxide is an OH group and the other end is a linear alkyl group having 15-24 carbon atoms, and wherein if a is the mole number of added ethylene oxide and b is the mole number of added propylene oxide, (a/b) is 1-2.
The compound (C) is at least one diisocyanate compound that is selected from the group consisting of compounds represented by formula (IV).
O=C=N-R2-N=C=O (IV)
(In formula (IV), R2 represents a methyl diphenylene group, a hexamethylene group, a methyl dicyclohexylene group, a 3-methyl-3, 5, 5-trimethyl cyclohexylene group, a dimethyl phenylene group or a tolylene group.)
