Procedure

In the same manner, there were conducted addition of 0.01 mole of lithium sec-butyl followed by polymerization at 60° C. for 60 minutes, addition of 200 g of a 50/50 by weight mixture of isoprene/butadiene followed by polymerization at 60° C. for 60 minutes and addition of 50 g of styrene followed by polymerization for 60 minutes, to obtain a styrene-isoprene/1,3-butadiene-styrene block copolymer. Hydrogenation was conducted in the same manner as above to obtain a block copolymer having a hydrogenation ratio of 98%. This was named SEEPS-1.
