WebPolybutylene (PB), also called polybutene-1 or poly-1-butene, is different from polybutenes or polyisobutylenes (PIB). PIB are amorphous and rubbery, and come in the form of a viscous liquid or big hard block (6 in. in length and width or could be higher). PB base polymers are supplied in the form of small pellets (about 1/4 in. in diameter) or ... WebButadiene (chemical formula C 4 H 6; chemical structure CH 2 =CH-CH=CH 2) 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 or Ziegler-Natta catalysts.
