Abstract:

The agglomeration of silica-silica in Si-SBR composites deteriorate the many properties of the tire tread rubber. We prepared various dispersants to improve the dispersibility of silica in Si-SBR composites:  poly (itaconic acid-coacrylamide), poly(styrene-co-allyl alcohol), poly(styrene-comethyl methacrylate), and poly(glycidyl methacrylate-costyrene). We confirmed the structure and molecular weight of the dispersants using FT-IR and GPC, respectively. The silica loading content in SBR/silica composites was determined using thermal gravimetric analysis. We also investigated curing characteristics, morphology, Payne effect of the Si-SBR composites according to the types of dispersant. As a result, we were able to compare the effect of silica dispersion in the composites.
