Abstract
A polymer polyol made by the reaction of an alkylene oxide adduct of a hydroxyl-containing amine, a polyether polyol of about 3000 to 8000 molecular weight and an organic polyisocyanate is disclosed. This polymer polyol may be used in the manufacture of flexible polyurethane foams. The polymer polyols are more stable than those made by other procedures.

A polymer polyol made by the reaction of an alkylene oxide adduct of a hydroxyl-containing amine, a polyether polyol of about 3000 to 8000 molecular weight and an organic polyisocyanate wherein the ratio of equivalents of alkylene oxide adduct of hydroxyl-containing amine to equivalents of polyisocyanate ranges from about 1 to 4 and wherein the combined weight of adduct and polyisocyanate is about 5 to 30 wt.% of the polyether polyol.
A method for the production of a polymer polyol consisting essentially of reacting an alkylene oxide adduct of a hydroxyl-containing amine, a polyether polyol of about 3000 to 8000 molecular weight and an organic polyisocyanate wherein the ratio of equivalents of alkylene oxide adduct of hydroxyl-containing amine to equivalents of polyisocyanate ranges from about 1 to 4 and wherein the combined weight of adduct and polyisocyanate is about 5 to 30 wt.% of the polyether polyol.
