Versuchsvorschrift

Norbornene, hydrocarbon-based solvent, ethylene and hydrogen was supplied to a continuous polymerization apparatus under the conditions that the norbornene concentration was 2.95 mol/L and the ethylene concentration was 1.05 mol/L and the ratio of hydrogen and ethylene was 0.21×10−3. At the same time, as the catalyst, racemic-isopropylidene-bis (tetrahydroindenyl) zirconium dichloride was supplied and, as a support catalyst, a catalyst system composed of methyalumoxane (10% toluene solution) was supplied to the reaction apparatus. The temperature of the reaction was maintained at 90° C. In the following step, the solvent was removed by high temperature and depressurization. The copolymer in a melt state was extruded in a strand shape, and the copolymer was cut into pellets having a length of 3 mm and a diameter of 2 mm. For the copolymerization, 0.6% antioxidant (trade name: Irganox 1010 manufactured by Chiba Special Chemicals Co. Ltd.) and 0.4% pentaerythritol tetrastearate were added.
