Kostelnik, R J

An improved process is described for preparing a hydrocarbon fluid friction reducing composition comprising mixing two or more alpha-monoolefins having 2 to about 30 carbon atoms in a diluent or an organic solvent and copolymerizing the alpha-monoolefins in the presence of a catalyst. The catalyst is comprised of a reducible or reduced titanium halide and an organo metal catalyst activator consisting of, per each 100 total moles of activator, about 1 to 20 moles of at least one trialkylaluminium compound, each alkyl group of which has 1 to 10 carbon atoms and about 99 to 80 moles of at least one dialkylaluminium halide compound, each alkyl group of which has 1 to about 10 carbon atoms. The mole ratio of activator to catalyst in the reaction mixture is in the range of about 0.001:1 to 50:1.
