実験手順

40 cc of toluene, 31 g of 1,3-butadiene and 27 g of 1,3-pentadiene have been added in a reactor to 0.42 g of nickel trifluoracetate chloride. After 4 hours of reaction at 60° C, we have isolated 50 g of a butadiene-pentadiene copolymer containing 60% of butadiene units and 40% of pentadiene units. Its microstructure consisted of more than 90% of 1,4 units and its average molecular weight by number was about 4,000 (polymer E).
