trans14polybutadiene

Trans14polybutadiene is a synthetic polymer characterized by a high proportion of trans-1,4 microstructure. This means that the double bonds within the polymer chain are arranged in a trans configuration along the backbone. This specific stereochemistry significantly influences the material's physical and mechanical properties compared to other polybutadiene isomers, such as cis-1,4-polybutadiene or 1,2-polybutadiene.

The trans-1,4-polybutadiene isomer typically exhibits a higher glass transition temperature and greater stiffness than its cis-isomer. This increased rigidity is due to the more linear and less coiled structure that the trans configuration imparts to the polymer chains. Consequently, trans14polybutadiene finds applications where a harder, less elastic rubbery material is desired.

Production of trans14polybutadiene involves specific polymerization catalysts, often based on transition metals like nickel or cobalt, under controlled conditions to favor the desired stereospecificity. Its properties make it suitable for use as a component in tire sidewalls, footwear, and certain types of impact modifiers for plastics. It can be blended with other elastomers to tailor the overall performance characteristics of the final composite material. The ability to control the microstructure is a key aspect of polymer synthesis for achieving desired material properties.
