  2. Butyl rubber - Wikipedia

    en.wikipedia.org/wiki/Butyl_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 based. Butyl rubber is produced by polymerization of about 98% of isobutylene with about 2% of isoprene.

  3. Polybutene - Wikipedia

    en.wikipedia.org/wiki/Polybutene

    Polybutene is an organic polymer made from a mixture of 1-butene, 2-butene, and isobutylene.Ethylene steam cracker C4s are also used as supplemental feed for polybutene. It is similar to polyisobutylene (PIB), which is produced from essentially pure isobutylene made in a C4 complex of a major refinery.

  4. Polyisobutene - Wikipedia

    en.wikipedia.org/wiki/Polyisobutene

    Polyisobutene (polyisobutylene) is a class of organic polymers prepared by polymerization of isobutene. The polymers often have the formula Me 3 C[CH 2 CMe 2] n H (Me = CH 3). They are typically colorless gummy solids. Cationic polymerization, initiated with a strong Brønsted or Lewis acid, is the typical method for its production.

    en.wikipedia.org/wiki/Isobutylene

    Isobutylene is used in the production of a variety of products. It is alkylated with butane to produce isooctane or dimerized to diisobutylene (DIB) and then hydrogenated to make isooctane, a fuel additive. Isobutylene is also used in the production of methacrolein.

    en.wikipedia.org/wiki/Polyolefin

    Polyolefin elastomer POE is used as a main ingredient in the molded flexible foam technology such as in the fabrication of self skinned footwear (for example, Crocs shoes), seat cushions, arm rests, spa pillows, etc. Hydrogenated polyalphaolefin (PAO) is used as a radar coolant. Head makes polyolefin tennis racket strings.

    From that month through January 2016, HPD issued more than 10,000 violations for dangerous lead paint conditions in units with children under 6, the age group most at risk of ingesting toxic paint. Half of the violations were in just 10 percent of the city’s zip codes, low-income neighborhoods in the Bronx, Brooklyn and northern Manhattan, a ...
