Application

Isoprene in the presence of sec-butyllithium as an initiator can undergo sequential anionic polymerization with styrene and methyl methacrylate to form polystyrene-block-polyisoprene-block-poly(methylmethacrylate) (SIM) and polyisoprene-block-polystyrene-block-poly(methyl methacrylate) (ISM), two asymmetric triblock terpolymers. It is also used in the asymmetric synthesis of polystyrene-block-polyisoprene (PS-b-PI) diblock copolymers.

Isoprene (2-methyl-1,3-butadiene) is emitted from many plants and it appears to have an adaptive role in protecting leaves from abiotic stress. However, only some species emit isoprene. Isoprene emission has appeared and been lost many times independently during the evolution
