- (2) a polyalkylene oxide polyol with a molecular weight between about 450 and about 30,000 and having a poly(oxyethylene) content greater than 70% wherein said polyalkylene oxide polyol is present in an amount from about 1 to about 10 weight percent based on the total weight of the polymer polyol; and
- (3) a stably dispersed polymer formed by the in situ polymerization of ethylenically unsaturated monomers within component (1) and/or component (2); wherein said polymer is present in an amount from about 2 to about 50 weight percent based on the total weight of the polymer polyol, wherein the mixture of (1) and (2) has an average nominal functionality of about 3.0 or greater and wherein the polymer polyol affords enhanced latitude for varying formulation components in the manufacture of flexible polyurethane foams with broad load and density ranges.
- 2. A polymer polyol which comprises:
- (1) a high functionality polyalkylene oxide polyol or blend of polyalkylene oxides with an equivalent weight between about 1200 and about 3000 and having an ethylene oxide content ranging from about 8 to about 25% percent; wherein said polyol or polyol blend is present in an amount from about 40 to about 90 weight percent based on the total weight of the polymer polyol;
- (2) a polyalkylene oxide polyol with a molecular weight between about 450 and 30,000 and having an ethylene oxide content of at least 70%; wherein said polyalkylene oxide polyol is present in an amount from about 1 to about 10 weight percent based on the total weight of the polymer polyol; and
- (3) a stably dispersed polymer formed by the in situ polymerization of ethylenically unsaturated monomers within component (1) and/or component (2); wherein said polymer is present in an amount from about 2 to about 50 weight percent based on the total weight of the polymer polyol, wherein the mixture of (1) and (2) has an average nominal functionality of from about 3.2 to about 6 and wherein the polymer polyol affords enhanced latitude for varying formulation components in the manufacture of flexible polyurethane foams with broad load and density ranges.
- 3. The polymer polyol of claim 1 wherein said high functionality polyol is a poly(oxyethylene-oxypropylene) copolymer.
- 4. The polymer polyol of claim 3 wherein said copolymer has an equivalent weight of form about 1600 to about 2200.
- 5. The polymer polyol of claim 1 wherein said subsidiary polyol is a poly(oxyethylene-oxypropylene) copolymer.
- 6. The polymer polyol of claim 1 wherein said subsidiary polyalkylene oxide has a molecular weight between about 450 and about 2000.
- 7. The polymer polyol of claim 1 wherein said subsidiary polyalkylene oxide has a functionality between about 2 and about 8.
- 8. The polymer polyol of claim 1 wherein said stably dispersed polymer is present in an amount of form about 4 to about 40 weight percent of the polymer polyol.
- 9. The polymer polyol of claim 1 wherein said high functionality polyol is an amine terminated polyol.
- 10. The polymer polyol of claim 1 wherein said high functionality polyol is a blend of an amine terminated polyol and another polyol.
- 11. The polymer polyol of claim 1 which contains a minor amount of an alkenoic acid grafted polyalkylene oxide.
- 12. The polymer polyol of claim 11 wherein the alkenoic acid is acrylic acid.
- 13. The polymer polyol of claim 11 wherein said grafted alkenoic acid in present in an amount of from about 0.01 to about 2 percent based on the total weight of said polymer polyol.
