Latest Patents

Stephen holds a patent for "Polyurethane foams prepared by a quasi-prepolymer technique." This invention relates to a method of preparing polyurethane foam, which involves forming an isocyanate-terminated prepolymer by reacting a polyisocyanate with a copolymer. The copolymer has an --OH-functionality greater than 2.00 but less than 3.00, derived from an epsilon-caprolactone, an epoxide, and a mixture of polyhydric alcohol chain initiators. The prepolymer is then reacted in the presence of a blowing agent and a catalyst with a reactant mixture that includes a chain-extending agent with at least two functional groups, each containing an active hydrogen atom, dissolved in a liquid copolymer of a lactone and an epoxide. The resulting polyurethane foams are particularly useful in the manufacture of shoe soles. Stephen has 1 patent to his name.
