The in situ Reaction of PSBR and the Correlation Study of Hybrid Elastomer

Abstract

Abstract: Pyridinium salt was produced by using reaction of vinylpyridine-SBR(PSBR) latex with propyl bromide, and then it reacted with aluminum alkoxide, alkyl titanate and active silanol to prepare a organic/inorganic hybrid elastomer latex(PSBR-M_nO_m). Akind of composite vulcanizate was obtained after the hybrid elastomer was compounded with natural rubber. Its mechanical performance is rather good and its hysteresis loss is quite high. In addition, it is similar in compression set to NR. Its structure was analyzed by FTIR, high-resolution NMR, DSC and TGetc .. It is believed that the existence of "huge metastable complexes" in the metal-containing composite vulcanizate may improve its mechanical properties.
