To disperse silica in SBR matrix, a need for adequate dispersant is long-standing. Proper interactions between SBR and silica are important for improving silica dispersibility between SBR and silica in medium. We prepared poly(glycidyl methacrylate-co-styrene) copolymer as a reactive dispersant by emulsion copolymerization using the sodium persulfate/ iron sulfate redox system. The structure of poly (GMA-costyrene) is an amphipathic copolymer composed of phenyl group and epoxy group. The glycidyl group of GMA and silanol one of Si formed a covalent bond resulting in improving the dispersion of silica in Si-SBR composites. We suggested a possible reaction mechanism for our system. We confirmed the structure of poly(GMA-co-styrene) copolymer using FT-IR spectroscopy. Also, we investigated dispersion effects in SiSBR composites according to the input molar ratio of monomer in copolymer and content of initiator.
