Polymerization of butadiene
Buta-1,3-diene can be polymerized to 1,4- or 1,2-polybutadiene with C1-C4 or C1-C2 bond formation. If the polymerization proceeds stereospecifically, eithercis- or trans1,4-polybutadiene or iso- or syndiotactic 1,2-polybutadiene.

- Note on the representation of the structural formulas
G. Natta succeeded for the first time in stereospecifically polymerizing butadiene using mixed metal-organic catalysts (Ziegler-Natta catalysts) and in demonstrating stereoregularity.Cis-1,4-polybutadiene has similar properties to natural rubber, the analogous isopropene polymer (cis-1,4-polyisoprene), and is used widely in industry, especially in the manufacture of car tires.
