摘要： A novel family of modified polyols suitable for use in the preparation of fluid polymer/polyols. The modified polyols are the reaction product obtained by reacting a silicon atom containing compound with an unmodified polyol, the silicon atom compound being one which has (a) at least olefinically unsatured hydrocarbyl group and (b) at least one functional group which is reactable with the hydroxy groups on the polyol. Examples of such silicon atom containing compounds include vinyltriethoxysilane and vinyltrimethoxysilane. Modified polyols of the type described are particularly useful in the preparation of polymer/polyols containing high levels of polymer since they reduce the viscosity of the final polymer/polyol and decrease the tendency of the polymer/polyol to produce polymer sediment.

摘要： A modified polyol, suitable for use as a non-aqueous dispersant in the preparation of polymer/polyols containing high levels of polymer, is provided. The modified polyol comprises the product obtained by reaction of a polyol with a coupling agent having at least two functional groups which are reactable with hydroxyl groups on the polyol.

摘要： A process for preparing a dispersion of a filler e.g., melamine, urea or borax in a dispersion or graft polymer polyol is provided. The process comprises (1) dispersing the filler in a suitable basestock (e.g., a polyether polyol) and (2) thereafter using this as the basestock for preparing the dispersion or graft polymer polyol.The polymer which is prepared in dispersed form in the second step may be for example (1) the reaction product of a polyamine, hydrazine or hydrazide and an isocyanate (PHD polymer) or (2) the reaction product of an olamine and an isocyanate (PIPA polymer). Alternatively styrene and acrylonitrile can be graft polymerised in the basestock in step (2). The new dispersion or graft polymer polyols containing dispersed filler are useful in the manufacture of fire resistant polyurethane foam for e.g., furniture applications.

摘要： Emulsions of oil and water are broken by treating them with a demulsifier which is a polysiloxane polyalkylene oxide copolymer in which the polyalkylene oxide segment is composed of random ethylene oxide and propylene oxide units.The demulsifier is particularly useful in breaking emulsions of water in crude oil which are normally difficult to separate and in breaking emulsions at relatively low temperatures, e.g. 30.degree. to 45.degree.

摘要： A process for preparing polyurea or polyurethane/urea foams from a polyamine or aminated polyether polyol is provided. The process comprises reacting the above component with a polyisocyanate (e.g. TDI, MDI etc.), a blowing agent (e.g. water) and a carboxylic acid or carboxylate acid salt. The function of the carboxylic acid or carboxylic acid salt is to slow down the reaction between the amine and the isocyanate so that effective foaming can take place before the reaction is completed.

摘要： Fluid polymer polyol dispersions which impart improved fire resistance to polyurethane foam. The fluid polymer polyol dispersions are prepared by grafting one or more monomers onto a polyol backbone with the difference that the grafting takes place in the presence of a flame retardant. During the grafting process the flame retardant is incorporated into the fluid polymer polyol dispersion. When such fluid polymer polyol dispersions are used, the fire resistance of the final polyurethane foam is improved relative to cases where a conventional fluid polymer polyol dispersion and a flame retardant are added separately to the polyurethane foam formulation.
