A stable polymer polyol made by the in situ polymerization of two or more monomers in a polyol blend wherein at least one monomer is a bifunctional compound containing both an isocyanate group and an ethylinically unsaturated group and wherein the polyol blend contains a base polyol and an amine terminated polyether which is more reactive with the bifunctional compound than is the base polyol.

Stable polymer/polyols made without macromonomer

Polyurea foams are prepared by the reaction of N-(polyoxyalkyl)-N-(alkyl)amines with organic isocyanates in the presence of a suitable catalyst.

Polyurea foams made from N-(polyoxyalkyl)-N-(alkyl)amines

This invention relates to silicon-based polymer/polyol stabilizers, processes for their manufacture and polyurethane foams containing these stabilized polymer polyols.

Silicone-based stabilizers useful in the preparation of improved

This invention describes novel molded flexible polyurethane foam surfactants which can be used in foam having high concentrations of reinforcing graft copolymer solids. The invention also describes the improved process for making these foams using the novel surfactants.

Polyether silicone copolymers with mixed hydroxy alkoxy capping for

This invention relates to a process for producing water-blown, flexible polyurethane foams for improved foam stability and molded water-blown, flexible polyurethane foams that are rapidly demoldable with improved green strength. The process involves the use of certain compounds ('foam modifiers') as hereinafter more specifically defined. The foam modifiers consist of an alkali metal or alkaline earth metal ion and an anion of a Bronsted acid having a pKa of greater than 1 (other than: (a) an inorganic alkaline earth metal salt that has a water solubility of less than one gram of salt per 100 milliliters of water at 25.degree. C., (b) alkali metal dihydrogen phosphate and (c) alkali metal sulphate).
