Silica-supported zirconocene/(perfluorophenyl)borate catalyst for propylene polymerization

IR spectroscopy has been used to study the interaction of silica with PhNEt2 (N) and B(C6F5)3 (B) and subsequent interaction of the support SiO2/[N + B] with dimethylzirconocene Me2Si(2-Me-Ind)2ZrMe2 (RL2ZrMe2). The data were obtained on the composition of the surface compounds appeared at both stages of catalyst synthesis.
