Abstract
A composition capable of providing a polyurethane resin having an improved lipophilic property which comprises an organic polyisocyanate compound, and a polyol component containing a polyether polyol having at least 10% by weight of units of an alkylene oxide having 6 or more carbon atoms, the polyether polyol having an excellent compatibility with an aliphatic hydrocarbon compound or with a hydroxy-terminated diene polymer, its hydrogenation product and a hydroxy-terminated olefin polymer.
Claims5
A polyurethane resin composition containing a polyurethane resin and an aliphatic hydrocarbon component, said composition being obtained by subjecting to reaction a mixture comprising:
- (A) a polyether polyol having at least 10% by weight of units of an alkylene oxide having 6 or more carbon atoms, or a mixture of said polyether polyol and a polyether polyol which does not have at least 10% by weight of units of an alkylene oxide having 6 or more carbon atoms, and
- (B) an organic polyisocyanate compound, in the presence of
- (C) an aliphatic hydrocarbon component.
