ABSTRACT:
Flame retardant graft polymers are prepared by graft polymerizing a phosphinyl-substituted acrylonitrile and at least one other vinyl monomer copolymerizable therewith in the presence of a rubber substrate. Polymers containing greater than 0.6% by weight, preferably 0.8 to 12.0% by weight, phosphorus exhibit flame retardant characteristics, which may be further improved by compounding with bis-halophenoxyalkanes.
