Abstract | dc.description.abstract | © 2018, Springer-Verlag GmbH Germany, part of Springer Nature. The preparation of nanocomposites, including styrene, tertbutylstyrene, and SiO2 nanoparticles, in toluene solution was attempted by in situ polymerization using a cyclopentadienyltitaniumtrichloride–methylaluminoxane, CpTiCl3–MAO, initiator system. SiO2 nanospheres (ca. 20 nm in diameter) were synthesized by the sol–gel method. The nanoparticles’ surface was modified with hexadecyltrimethoxysilane (Mod-SiO2Nps) in order to improve the interactions with the polymer. The polymerization activity increased as the proportion of p-methyl styrene was increased in the initial feed. With respect to the effect of the incorporation of nanoparticles in the reactions, the catalytic activity increased slightly in the presence of 5 wt% of nanospheres compared to neat copolymerization without any nanoparticles. Our studies achieved a convenient route through in situ polymerization, avoiding further treatment of the nanocomposite. The ther | |
