ABSTRACT:
The graft copolymer is the reaction of a backbone polymer having allylic chloride groups therein and monomers forming a pendant graft polymer in the presence of a coinitiator. The monomers have the formula ##STR1## wherein R is an alkyl group having from 1 to 15 carbon atoms, a cycloalkyl group having from 4 to 15 carbon atoms, an aryl group having from 6 to 15 carbon atoms, combinations thereof, or hydrogen. The amount of the pendant graft polymer portion by weight ranges from about 0.5 percent to about 90 percent based upon the total weight of the total graft copolymer with the pendant graft polymer being substituted on the polymer backbone in lieu of the chlorine atom of the allylic chloride group. The backbone polymer is selected from the class consisting of poly(vinyl chloride), polychloroprene, and unsaturated elastomers, the unsaturated elastomers being selected from the class consisting of chlorinated polydienes having repeating units containing from 4 to 12 carbon atoms, polychloroprene, chlorinated butyl rubber, chlorinated EPDM, chlorinated natural rubber, chlorinated styrene-butadiene rubber, and blends thereof.
