Abstract
A mixture of silicon and phosphorus are heated and reacted with halide to produce silicon tetrahalides, silicon-phosphorus halide and phosphorus trihalides compositions. These compositions are reacted with any suitable organic, inorganic-organic and/or inorganic compound to produce novel organic silicon-phosphorus containing compositions. These compositions may be utilized as flame retardants, coating agents, adhesives and many other uses.
