Abstract
A water permeability-imparting agent containing an alkylene oxide adduct (A) of a polyvalent active hydrogen compound represented by Formula (1): R—[O(A1O)m—(CH2CH2O)n—H]1 (1) wherein R represents a residue, after removal of all active hydrogen, of the polyvalent active hydrogen compound; A1O represents a C2 to C4 alkyleneoxy group; m represents an average addition mole number of A1O and is a number of 4 to 50; n represents an average addition mole number of CH2CH2O; and 1 represents a valence and is an integer of 3 to 6, and an average addition mole number ratio between A1O and CH2CH2O in Formula (1), n/m, is 0 to 0.5.
Claims11
A water permeability-imparting agent comprising:
- an alkylene oxide adduct (A) of a polyvalent active hydrogen compound represented by Formula (1):
- R—[O(A1O)m—(CH2CH2O)n—H]1 (1)
- wherein R represents a residue, after removal of all active hydrogen, of the polyvalent active hydrogen compound;
- A1O represents a C3 or C4 alkyleneoxy group;
- m represents an average addition mole number of A1O and is a number of 4 to 50;
- n represents an average addition mole number of CH2CH2O;
- and 1 represents a valence and is an integer of 3 to 6,
- an average addition mole number ratio between A1O and CH2CH2O in Formula (1), n/m, being 0 to 0.5, and
- the alkylene oxide adduct (A) of a polyvalent active hydrogen compound represented by Formula (1) is contained in an amount of 10 to 80% by weight based on the weight of the water permeability-imparting agent.
