ABSTRACT:
This invention relates to flame-retardant phosphorus-containing materials, particularly suitable for use as an additive, having little or no plasticizing effect, in flammable organic plastics. One such material may be made by reacting methallyl chloride with phenol or phenol-isopropylphenol blend and then phosphorylating. Another such material may be made by halogenating isopropyl groups of an isopropylphenyl phosphate blend and then dehydrohalogenating to make an isopropenyl-containing product, which may be oligomerized as by heating with a catalyst. The isopropenyl-containing product may also be employed as a flame-retarding comonomer.
