ABSTRACT:
A polymer polyol is produced by polymerizing a monomer having a polymerizable unsaturated group in a nitrogen bond-containing unsaturated polyol or polyol mixture having at least two nitrogen-containing bonds formed by reacting isocyanate groups with active hydrogen groups, at least one polymerizable unsaturated group and at least 1.7 hydroxyl groups, as average.
A polymer polyol is produced by polymerizing a monomer having a polymerizable unsaturated group in a nitrogen bond-containing unsaturated polyol or polyol mixture having at least 1.7 hydroxyl groups as average obtained by reacting a polyisocyanate with a mixture of a substantially saturated polyol having at least two hydroxyl groups and an unsaturated active hydrogen compound having at least one active hydrogen group and at least one polymerizable unsaturated group or by reacting said polyisocyanate with either of said substantially saturated polyol or said unsaturated active hydrogen compound and then reacting the remainder with the intermediate; or a polyol mixture obtained by diluting said nitrogen bond-containing unsaturated polyol or polyol mixture with a substantially saturated polyol.
