Abstract: Dispersions of silicate particles are formed in a polyol phase. The polyol, an alkoxysilane, water and catalyst are combined and reacted under specific temperature conditions to form the silicate particles in-situ in a liquid polyol phase. The dispersions are characterized in having excellent stability.

Abstract: Polyether polyols are prepared by polymerizing unsaturated monomers in a continuous phase of a base polyol. A macromer or polymerization produce of such a macromer is present during the polymerization to stabilize the polymer particles as they form. The macromer is a polyether capped with certain unsaturated epoxide compounds.

Abstract: A foam control agent comprising a linear polyorganosiloxane-polyoxyalkylene block copolymer comprising a single block of polyorganosiloxane having a DP of from 10 to 200 and a single block polyoxyalkylene block having a DP of from 2 to 60.

Abstract: Polyether diols characterized by a hydroxyl number of 56 or lower, high average functionality and high primary hydroxyl content are prepared by alkoxylating an unsaturated alcohol in multiple steps to form a polyether monol that contains 39% or more primary hydroxyl groups, and then reacting the polyether monol with a mercaptoalcohol that has a primary hydroxyl group.

Abstract: A polymeric foam precursor composition including the following components: (a) a di- or tri-functional (meth)acrylate oligomer (2); (b) a di- or higher-functional thiol compound (3); and (c) a borane compound (4) as initiator. The foam precursor composition can be isocyanate free, and the curing rate is largely moisture independent and can cure at low temperatures, below freezing point.

Abstract: Unsaturated polyether monols are removed from polyether polyols by reaction with a functionalized thiol compound or a polythiol compound. This process replaces the terminal unsaturation with a functional group, or else couples two or more of the monols to form a polyol. The functionality of the polyether polyol product is increased by the removal of the monols.
