ABSTRACT:
Novel styrene derivatives are disclosed of the formula: ##STR1## wherein R.sub.1 and R.sub.2 are the same or different and each represents a saturated aliphatic hydrocarbon group or an aromatic hydrocarbon group, and R.sub.3 is --OH, Cl, or a group of the formula --OR.sub.4 or ##STR2## wherein R.sub.4 represents a saturated aliphatic hydrocarbon group or an aromatic hydrocarbon group. The functionalized styrene monomers I as well as polymers and copolymers incorporating such monomer units are useful as initiators, or precursors thereof, for the polymerization of isobutylene under cationic conditions to give graft copolymers containing both styrenic and isobutylenic units. These copolymers have commercial applications such as rubbers, coatings, and lubricants.
