Abstract
The focus of this research is on the aromatic process oil, which works as a i) plasticizer thereby decreasing mixing torque and the production cost of the final compound; ii) extender of free volume in the compound so that lesser amount of polymer is needed for the final compound. The precise mechanism of action of the oil to achieve this is still unclear. Therefore, the aim here is to understand the influence of mineral-based aromatic process oil (0-20 phr) on the S-SBR/BR blends in terms of its plasticization and extension behavior. The plasticization behavior is revealed based on the change in glass transition temperature (Tg) studied with Broadband Dielectric Spectroscopy (BDS). While the extension behavior is explored based on changes in fractional free volume investigated with Positron Annihilation Lifetime Spectroscopy (PALS). The BDS analysis leads to a clearer understanding of the plasticization behavior of the oil by studying the change in Tg of each blend component. This is further supported with PALS results which verify the validity of the extension of the free volume associated with the plasticization of each blend component.
