Versuchsvorschrift
One operates under the same polymerization conditions in 250 cc. Steinie bottles, in heptane medium (123 g.) with 9.24 g. of isoprene and 3.08 g. of styrene (25% referred to the isoprene). Copolymerization is effected for 2 hours at 70° C. in the presence of 50 × 10-6 moles of active n-BuLi.
