DYNAMIC RHEOLOGICAL BEHAVIOR OF SSBR/SiO_2 COMPOUNDS
SSBR/SiO_2混炼胶的动态黏弹行为

Dynamic rheological behaviors of silica white (SiO2) filled solution-polymerized styrene-butadiene rubber (SSBR) compounds were investigated,and application of the time-concentration superposition (TCS) principle to this system was verified.Master curves were obtained by shifting the frequency sweep rheological data of the filled compounds with respect to the unfilled SSBR.The master curves disclosed the existence of modulus plateaus in the low frequency region while the complex viscosity exhibited marked s...
