50 ml dry toluene cosolvent, 7 ml 5-hexyl-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. After about 1 hour the reaction was shortstopped using a mixture of ethanolamine, Solution A and antioxidant solution. The polymer cement was coagulated using excess Solution A in a Waring blender. A solid weighing more than 5 grams was recovered after being filtered and vacuum dried at 60° C. It was a ring-opened 5-hexyl-2-norbornene/1-hexene copolymer having a DSV of about 1.03.
