Abstract
Polymer compositions formed by polymerizing a vinyl compound, e.g., a vinyl halide, a bis(hydrocarbyl)vinylphosphonate e.g., bis(beta-chloroethyl)vinylphosphonate, and an allyl halide, e.g., allyl chloride, find use as flame retardant plasticizers when the amount of allyl halide ranges between about 20% and 50% by weight and can be used as flame retardant solid additives when the amount of allyl halide ranges between about 5 and 20% by weight of the composition.
Claims14
A copolymer having flame retardant properties which consists essentially of:
- a. about 10 to 80% by weight of an alpha, beta-ethylenically unsaturated vinyl monomer selected from the group consisting of vinyl chloride, vinyl bromide, and vinyl acetate;
- b. about 2 to 80% by weight of a bis(hydrocarbyl) vinylphosphonate having the structure ##EQU3## wherein X is selected from the group consisting of hydrogen, halogen, cyano, aryl, C.sub.1 -C.sub.18 alkyl and ##EQU4## wherein R and R' are hydrocarbyl and hydrocarbyl groups containing non-interfering substituents consisting essentially of hydrogen and carbon and containing up to 18 carbon atoms;
- and
- c. about 5% to 50% by weight of an allyl halide selected from the group consisting of allyl chloride and allyl bromide.
