What is Butadiene rubber?

Butadiene rubber is rubber for general use.  It may be present in macromolecules in form of cis-1.4, trans-1.4 and 1.2 structural units. 1.2 units have pendant vinyl group, thus they may create isomeric forms (syndiotactic, isotactic or atactic). Content of individual forms of it structural units in polymeric chain depends on the polymerization method and type of used initiator and it determines basic properties of it. Trans-1.4 and also highly stereo regular 1.2-butadienes rubber does not have elastic properties. But these are owned by 1.2 isomers with lower stereo regularity degree that contain around 35-50 % of 1.2 structural units and with their properties they are similar to the SBR (styrene structural units are substituted by 1.2 units of butadiene). and also butadiene rubber with high content of cis-1.4 structural units has the best elastic properties. Presence of other structural units in this product significantly limits its crystallization ability, thus BR rubbers have low tensile strength.

Usage of Rubber Butadiene

The most usage of it is tire sidewall, floor covering-bicycle tire, foot wear, rubber toy, cable and rubber pipes. They are produced by butadiene.
