Reaction Steps
In a glove box, 18 mg of bisallyl nickel bromide (the catalyst B), 0.58 g of methylaluminoxane, and 15 g of toluene were mixed at room temperature under an argon atmosphere to adjust a catalyst solution. In the meantime, 8 g of 1,3-cyclohexadiene and 10 g of butadiene, as monomers, were dissolved into 15 g of toluene at room temperature under an argon atmosphere in a glove box. While this solution was kept to room temperature and was stirred, the total amount thereof was added to the total amount of the above-mentioned catalyst solution. Polymerization advanced promptly, and the reaction finished within 30 minutes. A slurry of the produced polymer was taken out from the glove box and added to a great deal of methanol acidified with hydrochloric acid to precipitate and isolate the polymer. Methanol was then removed by filtration. The resultant was vacuum-dried at room temperature for 24 hours to obtain 16 g of a cyclohexadiene-butadiene copolymer.
