Influence of the Crosslinking Content on the Structural Properties of Polybutadiene Rubbers with Different Isomeric Composition

Article Preview

Abstract:

In the present work first results on structural properties of three commercial isomers of polybutadiene rubber are presented. To this aim, rheometry, PALS, DSC and swelling techniques were used. Different samples were prepared containing diverse amounts of dycumil peroxide as crosslinking agent and vulcanized at 433 K.A correlation among the experimental results obtained using different techniques is also discussed.
