T o 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-co-
styrene) 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 Si-
SBR composites according to the input molar ratio of monomer
in copolymer and content of initiator.
