Abstract
Abstract Stable flame-retardant polyol-oxidated silicon-acidic boron emulsions are produced by mixing and reacting a liquid organic polyol, and oxidated silicon compound and an acidic boron compound. This flame-retardant emulsion is useful in the production of flame-retardant polyurethane, polyester and polyesteramide products.
