Metallation is accomplished with an alkyllithium compound and at least one activating reagent after a slurry of the copolymer in a nonreactive, saturated, nonpolar hydrocarbon solvent is first heated to a temperature greater than 80° Centigrade to provide {HEAD ~ the polymer} with {TAIL ~ an expanded settling volume} greater than its original settling volume
