Cao su Butadiene (Butadiene Rubber)
Butadiene rubber, synthetic rubber widely employed in tire treads for trucks and automobiles. It consists of polybutadiene, an elastomer (elastic polymer) built up by chemically linking multiple molecules of butadiene to form giant molecules, or polymers. The polymer is noted for its high resistance to abrasion, low heat buildup, and resistance to cracking.
Butadiene (chemical formula C4H6; chemical structure CH2=CH-CH=CH2) is a reactive colourless gas produced by the dehydrogenation of butene or butane or by the cracking of petroleum distillates. The gas is dissolved in hydrocarbon solvents and polymerized to polybutadiene by the action of anionic orZiegler-Natta catalysts. Like other dienes (hydrocarbons containing two double bonds in each molecule), butadiene is an isomer; that is, it can be produced with more than one molecular structure.
Two other structures are the trans-1,4 and the 1,2 side vinyl isomers.
Polybutadienes are made either with high cis content (95 to 97 percent) or with only 35 percent ciscontent along with 55 percent trans and 10 percent side vinyl. The properties of the two polymers are quite different. Although both display much higher resilience than other elastomers, the resilience of the mixed-isomer polymer is somewhat lower. In addition, the mixed polymer never crystallizes, so, without reinforcing fillers such as carbon black, products are weak and brittle. Both materials show good tack and abrasion resistance.
Much of the butadiene rubber produced is blended with natural rubber (polyisoprene) or with styrene-butadiene rubber to give it improved resilience and lower rolling resistance. More than half of all usage is in tires; other applications are footwear, wire and cable insulation, and conveyor belts. Polybutadiene is also processed with styrene monomer in order to produce high-impact polystyrene and with styrene and acrylonitrile monomer in order to produce a high-performance plastic known as acrylonitrile-butadiene-styrene copolymer.
