  2. Butyl rubber - Wikipedia

    en.wikipedia.org/wiki/Butyl_rubber

    Butyl rubber gloves. Butyl rubber, sometimes just called "butyl", is a synthetic rubber, a copolymer of isobutylene with isoprene. The abbreviation IIR stands for isobutylene isoprene rubber. Polyisobutylene, also known as "PIB" or polyisobutene, (C 4 H 8) n, is the homopolymer of isobutylene, or 2-methyl-1-propene, on which butyl rubber is ...

  3. Isobutylene - Wikipedia

    en.wikipedia.org/wiki/Isobutylene

    Polymerization of isobutylene produces butyl rubber (polyisobutylene or PIB). Antioxidants such as butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA) are produced by Friedel-Crafts alkylation of phenols with isobutylene. tert-Butylamine is produced commercially by amination of isobutylene using zeolite catalysts: [6]

    en.wikipedia.org/wiki/Talk:Butyl_rubber

    Butyl rubber (IIR) is a copolymer and an elastomer, Polyisobutylene (also called Polyisobutene (PIB)) however is a homopolymer and thermoplastic. I think the information given in this article concerning PIB should be moved to the already existing text Polyisobutene .

  6. Sulfur vulcanization - Wikipedia

    en.wikipedia.org/wiki/Sulfur_vulcanization

    Other specialty rubbers may also be vulcanized, such as nitrile rubber (NBR) and butyl rubber (IIR). Vulcanization, in common with the curing of other thermosetting polymers, is generally irreversible. Efforts have focussed on developing de-vulcanization (see tire recycling) processes for recycling of rubber waste but with little success.

  7. Cationic polymerization - Wikipedia

    en.wikipedia.org/wiki/Cationic_polymerization

    Butyl rubber gloves. Butyl rubber, in contrast to PIB, is a copolymer in which the monomers isobutylene (~98%) and isoprene (2%) are polymerized in a process similar to high molecular weight PIBs. Butyl rubber polymerization is carried out as a continuous process with AlCl 3 as the initiator. Its low gas permeability and good resistance to ...
