Isoprene → 2-Methylbuta-1,3-diene--2-methylprop-1-ene (1/1)

Participants

Reaction Steps

The methodology of Example 3 was repeated, except that 1.5 mL of isoprene was added to the reaction vessel prior to initiation. The mixture was allowed to stir at −78° C. for 10 minutes, before addition of methanol (10 mL) to terminate the reaction. The yield of copolymer was 5.5 g (Mn=104,000, Mw=203,000). The isoprene content in the rubber was 1.5 mol-percent.
