Graft copolymers of para-alkylstyrene/isoolefin copolymers
First Claim
1. A graft copolymer comprising ##STR77## wherein R and R'"'"' are independently selected from the group consisting of hydrogen, alkyl, and the primary and secondary alkyl halides, a ranges from about 14 to 70,000, b ranges from 0 to about 70,000, c ranges from 0 to about 70,000, d ranges from 1 to 70,000, X comprises a halogen, and Nu comprises a nucleophilic residue provided by a thermoplastic polymeric nucleophile having a molecular weight of at least 1,000 and being sufficiently nucleophilic such that said nucleophile is capable of donating electrons to benzyl halides.
