2500 ml dry toluene cosolvent, 350 ml 5,6-dimethyl-2-norbornene, 20 ml 1-hexene solution, and 45 ml diethylaluminum iodide solution were charged to a dry, nitrogen-purged glass gallon reactor. 56 ml of the MoCl5 solution was charged last with shaking. After 1.5 hours the reaction was shortstopped using a mixture of 5 ml ethanolamine, 15 ml Solution A, 60 ml of an antioxidant solution (0.1 g/ml of 2,2'-methylenebis-[4-methyl-6-t-butylphenol] in toluene), and 100 ml toluene. The polymer cement was coagulated batch-wise in a Waring blender using excess Solution A. 270 grams of a solid, ring-opened 5,6-dimethyl-2-norbornene/1-hexene copolymer was recovered after being filtered and vacuum dried at 60° C.
