実験手順

50 ml dry toluene cosolvent, 7 ml 5-octyl-2-norbornene (containing about 15 wt.% dicyclopentadiene trimer impurity), 8 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 2 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. The solid recovered after being filtered and vacuum dried at 60° C. was found to be a terpolymer of octylnorbornene, dicyclopentadiene trimer and 1-hexene. Tg was measured and the value adjusted to compensate for the trimer impurity.
