  • Patent number: 6265456
    Abstract: An improved process is provided for the preparation of siloxane-oxyalkylene and siloxane-alkyl copolymer compositions via a hydrosilation reaction in the presence of high boiling point natural vegetable oils as the reaction solvent. The reaction solvent need not be removed from the block copolymer product, and indeed is beneficial to remain with the copolymer particularly when the copolymer is used as a surfactant for polyurethane foam formulations. Soybean oil and linseed oil are the preferred high boiling natural oil solvents when the copolymer product is to be used in the preparation of the surfactants for polyurethane foams. High resiliency polyurethane foam prepared with these natural oils present in the surfactant preparation afforded improved compression sets, wet compression sets and humid aged compression sets.
