Polyisobutylene

WebPolyisobutylene, sometimes called butyl rubber, and other times PIB, is a vinyl polymer. It's very similar to polyethylene and polypropylene in structure, except that every other carbon is substituted with two methyl groups. It is made from the monomer isobutylene, by cationic vinyl polymerization. WebJan 31, 2024 · Saudi Aramco with its partner Total today announced the signing of a Memorandum of Understanding (MoU) with Daelim, a South Korean petrochemical company. Under the MoU, Daelim is planning to build a new 80,000 tons state-of-the-art Polyisobutylene (PIB) plant, which is expected to come on-stream in 2024.

WebJun 10, 2024 · Polyisobutylene is a synthetic rubber, or elastomer. It is the only rubber that is gas impermeable. Because polyisobutylene will hold air, it is used to make things like the inner liner of tires and basketballs. Draw a curved arrow mechanism for the acid-catalyzed polymerization of 2-methylpropene (isobutylene). 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, (C4H8)n, is the homopolymer of isobutylene, or 2-methyl-1-propene, on which butyl rubber is based.
