  • Color reduction of polymethylene poly (phenylisocyanates)
    Patent number: 6166128
    Abstract: This invention relates to a process for the reduction of color of polymethylene poly(phenylisocyanates). This process comprises mixing a polymethylene poly(phenylisocyanate) with an epoxide having an epoxide equivalent weight of about 44 to about 700, and heating this mixture to a temperature of from about 35 to about 150.degree. C. for at least about 15 minutes, with stirring. Suitable epoxides include epoxidized fatty acid monoglycerides, epoxidized fatty acid diglycerides, epoxidized fatty acid triglycerides, epoxidized dimer fatty acids and epoxidized trimer fatty acids.

  • Isocyanate-terminated prepolymers and rigid-foams produced therefrom
    Patent number: 5962541
    Abstract: NCO-terminated prepolymers are made by reacting a polymeric diphenylmethane diisocyanate (PMDI) and a polyol having a functionality of from about 1.8 to about 4.0 and a molecular weight of from about 400 to about 2,000. The PMDI and polyol are reacted in amounts such that the equivalent ratio of isocyanate groups to hydroxyl groups is from about 15:1 to about 160:1. These prepolymers are useful in the production of polyurethane foams, particularly laminated foams.
