Abstract

Composition and catalytic properties in ethylene polymerization of supported systems prepared via the interaction of Ti(CH2C6H5)3X (X=F, Cl, Br) and Zr(CH2C6H5)2Cl2 complexes with silica and alumina have been studied. Halide addition to benzyl complexes decreases the polymer molecular mass.

Abstract

Исследован состав и каталитические свойства в полимеризации этилена нанесённых систем, полученных при взаимодействии комплексов состава Ti(CH2C6H5)3X (X=F, Cl, Br) и Zr(CH2C6H5)2Cl2 с SiO2 и Al2O3. Показано, что введение галоида в состав бензильных комплексов приводит к снижению молекулярной массы полимера.
