US 5,703,258 A · Silicon and phosphorus containing compositions

Abstract

A flame retardant organic silicon and phosphorus containing compound is produced by reacting a silicon halides compound with an organic phosphorus compound to produce an organic silicon and phosphorus halides compound which is then reacted with an organic compound to produce an organic silicon and phosphorus containing compound. This organic silicon and phosphorus containing compound is incorporated in an otherwise more flammable organic material under reaction conditions and in an amount sufficient to reduce the combustibility of the otherwise more flammable organic material. The organic silicon and phosphorus containing compound may also be utilized as coating agents, adhesives, surfactants, insecticides, hydraulic fluid and other uses.
