数据库记载的用途

  • Used as a monomer to manufacture polyisoprene and butyl rubber; [HSDB]
  • Almost all isoprene produced is used for the preparation of polymers or copolymers. cis-Polyisoprene is the largest application with SIS block polymers a secondary application, and butyl rubber is a significant third application.
  • Smaller amounts are used as an intermediate into specialty chemicals, including vitamins, pharmaceuticals, flavorings, and perfumes, and epoxy hardeners.
  • Most of the isoprene that is produced is utilized for the synthesis of poly(cis-1,4-isoprene) (isoprene rubber, IR), a material (particularly the titanium type) that closely resembles natural rubber in both structure and properties. This IR is largely used for the production of vehicle tires. ... The second largest market for isoprene is the manufacture of styrene - isoprene - styrene (SIS) block copolymers ... These products are especially useful as thermoplastic rubbers and as pressure-sensitive or thermosetting
  • Manufacture of "synthetic" natural rubber, butyl rubber. Copolymer in the production of synthetic elastomers.
