Modification of Polybutadiene Latex Particles with Sulfidosilane Moieties

In this work, the surface of polybutadiene latex particles was modified with an organosilane coupling agent.The functionalization was carried out by using bis[3-(triethoxysilyl) propy] tetrasulfide (TESPT) in the presence of zinc oxide as an activator. This reaction was studied by the Fourier Transform Infrared (ATRFTIR) spectra, Raman spectroscopy and particle size analysis. In ATR-FTIR spectra, the C-S bond at 624 cm-1 appeared after a period of time. The presence of sulfur in synthesized sample confirmed with elemental analysis (CHNSO). Thermogravimetric analysis (TGA) used to investigate thermal properties and grafting degree of silane moieties on functionalized latex particles. In this study, it is believed that the modification of polybutadiene latex particles was happened in a reaction like prevulcanization
