ПОЛИМЕРИЗАЦИЯ ПРОПИЛЕНА В ЖИДКОМ МОНОМЕРЕ В ПРИСУТСТВИИ СОВРЕМЕННЫХ ВЫСОКОЭФФЕКТИВНЫХ ТИТАНМАГНИЕВЫХ КАТАЛИЗАТОРОВ

In vitro the comparative studies of propylene polymerization in liquid monomer on the titanium-magnesium catalyst IK-8-21, developed at the Boreskov Institute of Catalysis and on imported industrial catalysts (codename – ТМК-1, -2, -3) were carried out. The activity and stereo-specificity of the catalyst were estimated, also the properties of the resulting polypropylene: granulometric composition, physical and mechanical characteristics. It is shown that the catalytic properties of IK-8-21 catalyst are not inferior to foreign analogues in the synthesis of the polypropylene. Polypropylene powder produced on IK-8-21 is homogeneous and has a good morphology. Physical and mechanical properties of polypropylene synthesized in the domestic catalyst IK-8-21 close to those for polypropylene produced using imported catalyst TMK-1.
