A siloxane-containing 2-vinylpyridine–styrene–butadiene copolymer (PSBR/WG) was prepared from a 2-vinylpyridine–styrene–butadiene copolymer (PSBR) latex and water glass. The water glass was added slowly, with stirring, to the PSBR latex. The latex mixture was stirred for 3 h at room temperature, and then, it was coagulated with 1Nsulfuric acid producing a sulfate of PSBR with siloxane. The physical properties, such as the filling and stiffening effects of the hybrid polymer, and the vulcanizates were improved. An important advantage of this system is that it is possible to prepare the hybrid polymer simply, and the sodium ions formed in the reaction can also be easily removed.
