ABSTRACT:
There is provided a method of introducing ethylenically unsaturated functionality, into an alkylstyrene homopolymer or copolymer with an isoolefin, at the alkylbenzyl carbon atom comprising the steps of: forming a solution of the polymer in a hydrocarbon solvent; adding to the polymer solution an alkali metal (Na, K, Rb, Cs) alkoxide and an alkyl lithium compound to form a solution of a metalated intermediate; and adding a halodialkylalkenyl silane to the metalated polymer solution. Also provided are the ethylenically unsaturated functionalized polymer derivatives made by the method, and the crosslinked derivatives thereof.
