The polymerization reaction was conducted in a 300 ml stainless autoclave equipped with a mechanical stirrer. The reactor was initially charged with 50 ml of toluene, 5 ml of 1-octene, 5 ml of styrene, and various quantities of 1,7-octadiene (1.6 ml, 0.8 ml, 0.4 ml, 0.2 ml and 0.1 ml) in an argon filled dry-box. The reactor was then sealed and then moved from the dry box and purged with nitrogen gas at 30° C. About 0.101 g of TiCl3(AA) and 1 ml of AlCl2Et in 10 ml of toluene after sufficiently stirring were introduced under nitrogen pressure to initiate the polymerization. After about 1 hour, the reaction was terminated by adding 100 ml of dilute HCl solution in methanol to the reactor. The polymers were isolated by filtration and washed completely with methanol and dried under vacuum for about 8 hours. The 1-octene/styrene/1,7-octadiene terpolymers were completely soluble in common organic solvents, including toluene and decalin.
