2. Butyl rubber - Wikipedia

   en.wikipedia.org/wiki/Butyl_rubber

   Butyl rubber is one of the most robust elastomers when subjected to chemical warfare agents and decontamination materials. It is a harder and less porous material than other elastomers, such as natural rubber or silicone, but still has enough elasticity to form an airtight seal.

3. Solution polymerization - Wikipedia

   en.wikipedia.org/wiki/Solution_polymerization

   Butyl rubber (IIR) by low temperature cationic copolymerization of isobutylene with isoprene in ethylene or methylchloride solution. Aromatic polyamides (e.g. Kevlar and Nomex ) are made by polycondensation in N -methyl-pyrrolidone and calcium chloride solution.

4. Cationic polymerization - Wikipedia

   en.wikipedia.org/wiki/Cationic_polymerization

   The main chemical companies that produce polyisobutylene are Esso, ExxonMobil, and BASF. [14] 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

5. Isobutylene - Wikipedia

   en.wikipedia.org/wiki/Isobutylene

   Isobutylene (or 2-methylpropene) is a hydrocarbon with the chemical formula (CH 3) 2 C=CH 2. It is a four-carbon branched alkene (olefin), one of the four isomers of butylene . It is a colorless flammable gas, and is of considerable industrial value.

6. List of gasoline additives - Wikipedia

   Butyl rubber (as polyisobutylene succinimide, detergent to prevent fouling of diesel fuel injectors) Ferrous picrate, used in diesel fuel to increase fuel conversion efficiency and reduce emissions; Two-stroke oil, for lubrication of small engines reliant on crankcase compression; Upper cylinder lubricant, extensively advertised but of unproven ...

7. Elastomer - Wikipedia

   en.wikipedia.org/wiki/Elastomer

   Chloroprene rubber (CR), polychloroprene, neoprene; Butyl rubber (copolymer of isobutene and isoprene, IIR) Halogenated butyl rubbers (chloro butyl rubber: CIIR; bromo butyl rubber: BIIR) Styrene-butadiene rubber (copolymer of styrene and butadiene, SBR) Nitrile rubber (copolymer of butadiene and acrylonitrile, NBR), also called Buna N rubbers

8. Synthetic rubber - Wikipedia

   en.wikipedia.org/wiki/Synthetic_rubber

   Examples include Viton rubber, EPDM and butyl rubber. A new class of synthetic rubber is the thermoplastic elastomers which can be moulded easily unlike conventional natural rubber vulcanized rubber. Their structure is stabilized by cross-linking by crystallites in the case of polyurethanes or by amorphous domains in the case of SBS block ...

9. Butyl group - Wikipedia

   en.wikipedia.org/wiki/Butyl_group

   In organic chemistry, butyl is a four-carbon alkyl radical or substituent group with general chemical formula −C 4 H 9, derived from either of the two isomers (n-butane and isobutane) of butane. The isomer n -butane can connect in two ways, giving rise to two "-butyl" groups:
