A catalyst is prepared by combining, in a primarily nitrogen environment under ambient temperature and pressure, 0.090 grams of TiCl3.AA with 1.0 milliliters of purified petroleum distillate, together with 83 microliters of dibutyl ether promoter according to the teachings of Mack U.S. Pat. No. 4,416,714. The solution is held for 30 minutes while stirring. The catalyst is then activated using 0.89 milliliters of an aluminum cocatalyst, a 25% solution of diisobutyl aluminum chloride (DIBAC) in heptane solvent (“25% DIBAC solution”). Again, the mixture is held for 30 minutes while stirring. An octene-decene copolymer is prepared in primarily nitrogen environment under standard temperature and pressure by mixing 572 ml of purified petroleum distillate, 42.9 milliliters of 1-octene, and 5.7 milliliters of 1-decene in a beaker. After stirring, 3.3 milliliters of a 25% DIBAC solution is added to the solvent and mixed olefins in the beaker. The mixture is held for 30 minutes with stirring. The entire 1.0 milliliter of catalyst mixture prepared is added to the beaker while the contents are being stirred. The entire mixture is allowed to react and as the solution becomes viscous, the agitation is discontinued. The copolymer is subsequently tested. Conversion to polymer is greater than 95% and the inherent viscosity is sufficient for good drag reduction.
