Name the type of polymerization but-1-ene undergoes
Answers
Explanation:
There are four isomers of alkenes, which have the chemical formula C4H8, but different structures. The IUPAC (and common) names, respectively, are: but-1-ene (α-butylene), cis-but-2-ene (cis-β -butylene), trans-but-2-ene (trans-β -butylene) and 2-methylpropene (isobutylene). Because of the double bonds, these four-carbon alkenes can act as monomers in the formation of polymers, and have other uses as petrochemical intermediates. They are used in the production of synthetic rubber. But-1-ene is a linear or normal α-olefin and isobutylene is a branched α-olefin. In a rather low percentage, but-1-ene is used as one of the co-monomers, along with other α-olefins, in the production of high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE). Butyl rubber is made by cationic polymerisation of isobutylene with between 2 and 7% isoprene. Isobutylene is also used for the production of methyl tert-butyl ether (MTBE) and isooctane, both of which improve the octane rating/combustion of gasoline used to power automotives.
