Infrared dichroism and birefringence studies of silica-filled styrene-butadiene rubbers
Infrared and birefringence measurements are used to characterize the orientational behavior of silica-filled styrene-butadiene copolymers. The orientational data are correlated with the results of equilibrium swelling measurements. On the other hand, the role played by a silane couling agent bis(3-triethoxysilylpropyl)tetrasulfide (TESPT), or "Si69") on rubber/silica system is discussed.
