In a reactor, a mixture of 57 g of 1,3-butadiene and 37 g of isoprene is added to a solution of 12.5 mmoles of butyllithium in 250 ml of n-heptane. The reaction mixture is stirred for 5 hours at 50° C., which results in a complete conversion of the monomers to a butadiene-isoprene copolymer having a butadiene content of 60% by weight and an average molecular weight by number of 5700.
