Water-soluble polyurethane according to the present invention is obtained from polyalkylene glycols, diisocyanates, and comb-shaped hydrophobic diols represented by the following general formula (3):
1
wherein each of R
1
, R
2
and R
3
is a hydrocarbon group; each of Y and Y′ is hydrogen, a methyl group or a CH
2
Cl group; each of Z and Z′ is oxygen, sulfur or a CH
2
group; n is an integer of 0 to 15 when Z is oxygen and is 0 when Z is sulfur or a CH
2
group; n′ is an integer of 0 to 15 when Z′ is oxygen and is 0 when Z′ is sulfur or a CH
2
group.
The water-soluble polyurethane is used as, for example, an extruding auxiliary for cement materials, a mortar thickening agent, an underwater concrete thickening agent, a ceramics forming binder and a moisturizer for hair cosmetics, all of which are characterized by excellent water retention and high shape retention.
