Claim Text:
1. A method of making a functionalized random interpolymer, said interpolymer comprising polyene and styrenic mer units, said method comprising (a) in a reaction vessel that contains ingredients which comprise a non-polar solvent, a polar coordinator compound, and unsaturated monomers that comprise one or more polyenes and a sufficient amount of one or more hydrocarbon styrenes so as to provide about 20 to about 40% of the constituent mer units of said interpolymer, initiating polymerization of said unsaturated monomers with an effective amount of an initiating compound having the general formula where and (b) hydrolyzing each of said protecting groups by reaction with tetrabutylammonium fluoride, thereby providing said functionalized random interpolymer.
