Definition
ChEBI: A macromolecule composed of repeating but-2-ene-1,4-diyl units.
Production Methods
The production of polybutadiene involves copolymerizing
three parts butadiene and one part styrene. Also present in
small amounts is an initiator or catalyst, which is usually a
peroxide, and a chain-modifying agent such as dodecyl
mercaptan. Isotactic cis-1,4 polybutadiene has been synthesized
using a titanium halide such as titanium tetrachloride or
titanium tetrabromide; using a cobalt salt of octanoate or
napthenate, or complexes with pyridine; or using nickel
halide catalyst based on boron trifluoride reduced by aluminum
alkyls.
General Description
Polybutadiene is a synthetic rubber that is produced by solution polymerization of 1,3-butadiene. It has excellent mechanical properties which include low temperature flexibility and abrasion resistance. It can be cured by using sulfur based donors and peroxides to result in a highly cross-linked polymer with high resilience.
Carcinogenicity
The individual oil extenders are
classified as suspected human carcinogens.
