An approach to chemorheology of a filled SBR compound

Three steps in complex chemorheological studies are necessary for complete rheological characterization of filled rubbers during cross-linking reactio n. They include: (i) kinetic studies of cross-linking reaction, (ii) theolo gical studies of green rubber compounds, and (iii) correlation between the rheological parameters and the degree of cure. Basic experiments in the ste ps (i)-(iii) and their modeling are presented in this paper on the example of a filled SBR compound with sulfur accelerated vulcanization. The approac h provides a unique possibility to trace the rheological properties of rubb er compounds from the green to completely cured states.
