  • Patent number: 5177119
    Abstract: A novel polyurethane resin foam composition is provided which is only water-blown and requires no chlorofluorocarbon or other auxiliary blowing agents, yet suffers little or no degradation in physical properties even at reduced isocyanate indexes. The formulation includes a relatively low molecular weight polyethylene glycol along with the conventional polyol to make a blend for the polyol component. The molecular weight range of the polyethylene glycol is from about 200 to about 600. The lower molecular weight polyethylene glycol may range from about 2 to about 10 parts by weight of the polyol, based on the total polyurethane foam composition.

  • Patent number: 4785026
    Abstract: Polymer polyols with high polymer or solids content made by the reaction of alkanolamines with polyisocyanates in a dispersing media of polymer polyols created from vinyl monomers in a conventional manner. The equivalents of alkanolamine to equivalents of polyisocyanate ranges from about 1/1 to 5/1 to give novel polymer polyols with solid contents from about 25% to up to 50%. Polyurethane foams made employing the novel polymer polyols of the present invention have higher load bearing properties, and provide a good balance between the load bearing properties and the open cell content of the foam to provide a stable foam, as compared with those employing only conventional polymer polyols.

  • Patent number: 4785127
    Abstract: A vinyl polymer polyol is prepared by the free radical initiated polymerization of vinyl monomers using partially alkoxylated polyoxyalkyleneamines as the dispersing media. The vinyl polymer polyols of this invention give faster curing flexible polyurethane foams with improved load-bearing properties.

  • Patent number: 4433067
    Abstract: The invention relates to reaction injection molded elastomers containing a major amount of polyurea linkages derived from high molecular weight amine terminated polyethers, an aromatic diamine chain extender and a polyisocyanate. The reaction injection molded (RIM) elastomers of this invention are useful, for example, as automobile body parts.
