Butadiene Rubber (BR) is commercially available in two main forms, one containing 1,4-cis repeating unit levels around 40%, which is called low-cis BR, and one with levels that range from 92 to 98%, called high-cis BR. Moreover, high-vinyl polybutadienes may be obtained, which contains pendent vinyl groups as a result of 1,2-polymerisation mechanisms. These rubbers had properties similar to those of SBR, different cure behaviour, and are used with a specific compounding strategy. In addition, besides traditional BR grades, using a proprietary technology, new Nd-based polybutadienes containing a specially designed branching architecture was produces, to optimize processing and performance at the same time. The molecular architecture able to conjugate those extremely different aspects was determined on the basis of polymer dynamics through linear viscoelastic relaxation time spectrum and nonlinear viscoelastic extensional rheology. By considering various recipes, advantages in terms of compound viscosity, filler incorporation and extrusion behavior are addressed together with usual testing parameters. The filler dispersion is commented on the basis of dynamic-mechanical approach.
