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