    Abstract: This invention relates to a process for forming an allophanate-modified polymethylene poly(phenylisocyanate) comprising the steps of reacting a small amount of epoxide, along with alcohol, to polymethylene poly(phenylisocyanate) (PMDI) to form an intermediate, which is converted to allophanate upon addition of a metal divalent catalyst. This invention also relates to a process for forming an allophanate-modified PMDI comprising the steps of adding a small amount of epoxide, to PMDI to form an intermediate, which is converted to allophanate upon addition of an alcohol and a metal divalent catalyst. Both processes according to the invention of preparing allophanate-modified PMDI use mild conditions and low catalyst levels to yield viscosity stable products.

    Abstract: This invention relates to novel polyether polyols and to a process for their production. These polyether polyols are prepared by forming a polyhydroxyl group containing component in a first step by the reaction of a triazole-group containing compound with a compound that contains at least one functional group that is capable of reacting with the amine groups of the triazole group containing compound, and reacting the hydroxyl-group containing component with an alkylene oxide to form the polyether polyol of the invention. The present invention also relates to isocyanate-reactive compositions comprising these novel polyether polyols, and to a process for the production of a polyurethane comprising reacting a polyisocyanate with the novel polyether polyols of the present invention.
