Document Type and Number:
WIPO Patent Application WO/2010/140566
Kind Code:
A1
Abstract:
Disclosed is a polyurethane polymer solution containing a polyurethane polymer and an organic solvent, and a method for manufacturing the same. The polyurethane polymer is obtained by reacting at least a polyisocyanate compound (c) and a polycarbonate polyol (a) that contains a repeating unit represented by general formula (1) and has hydroxyl groups at both terminals. (In the formula, Z1 and Z2 independently represent an optionally-substituted bivalent aliphatic hydrocarbon group having 1 to 10 carbon atoms.)
