ISOPRENE, TERPENES AND NATURAL ALKENES AND ALKYNES ETHYLENE The simplest alkene, ethene, is produced naturally by all higher plants from the amino acid methionine and is a plant growth regulator.


Almost all isoprene produced is used in the preparation of polymers and copolymers. cis-Polyisoprene, primarily for vehicle tyres, is the largest application, with styrene-isoprene-styrene (SIS) block polymers being a rapidly growing secondary application.
