50 ml dry toluene cosolvent, 7 ml 5-butyl-2-norbornene, 0.5 ml 1-hexene solution, and 0.6 ml diethylaluminum iodide solution were charged to a dry, nitrogen-purged 7 oz. bottle. 0.75 ml of the MoCl5 solution was charged last with shaking. After 0.5 hour the reaction was shortstopped using a mixture of 0.1 ml ethanolamine, 0.5 ml Solution A and 1 ml of an antioxidant solution (0.1 g/ml of 2,2'-methylenebis-[4-methyl-6-t-butylphenol] in toluene). The polymer cement was coagulated using excess Solution A in a Waring blender. A solid weighing 6.4 grams was recovered after being filtered and vacuum dried at 60° C. It was found to be a ring-opened 5-butyl-2-norbornene/1-hexene copolymer having a DSV of about 0.88.
