Isoprene is a common organic compound. It is the monomer of natural rubber and also a common structure motif to an immense variety of other naturally occurring compounds, collectively termed the isoprenoids. Polyisoprenes are used in a wide variety of rubber applications including medical equipment, baby bottle nipples, toys, shoe soles, tires, elastic films and threads for golf balls or textiles. Other uses include adhesives, paints and coatings. Styrene-isoprene rubber is a copolymer that is used in pressure sensitive adhesives.
