More Information
Summary:Siloxane-polyether copolymer surfactants for manufacture of high resiliency polyurethane foam which are capped with t-butyl groups on the ends of the polyether blocks, polyurethane foam compositions containing such surfactants, a method for making polyurethane foam using such surfactants, and polyurethane foam made the method are disclosed and claimed. The t-butyl-capped surfactants afford improved surfactant potencies and foam breathabilities relative to the commonly-employed methyl-capped surfactants.
