AN APPROACH TO CHEMORHEOLOGY OF A FILLED SBR COMPOUND

Three steps in complex chemurheological studies are necessary for complete rheological characicrization of filled rubbers during cross-linking reaction. They include: (i) kinetic studies of cross-linking reaction, (ii) rheological studies of green rubber compounds, and (iii) correlalion between therheological parameters and the degree of cure. Basic experiments in the steps (i)-(iii) and [heir modeling are presented in this paper on the example of a filled SBR compound with sulfur accelerated vulcanization. The approach provides a unique possibility lo trace the rheological properties of rubber compounds from the green to completely cured states.
