METHOD OF OLEFIN POLYMERIZATION AND CATALYTIC SYSTEM Russian patent published in 2002 - IPC

Abstract RU 2193042 C2

FIELD: polymers, chemical technology. SUBSTANCE: invention relates to polymerization of olefins using metallocenes. In the most preferable variants of realization the invention relates to polymerization of olefins comprising 3 carbon atoms, not less. Invention describes method of olefins polymerization involving interaction of olefin with catalytic system obtained by combination of cocatalyst and metallocene of metals of group IVB taken among bis-(2-aryltetrahydro-indenyl)-metallocenes where aryl group is unsubstituted or substituted with hydrocarbon group containing hydroxy-group. Invention describes also catalytic system prepared by metallocene compound taken among bis-(2-aryltetrahydroindenyl)-metallocenes where aryl group is unsubstituted or substituted with hydrocarbon group containing hydroxy-group. Invention provides synthesis of polymers characterizing with high content of isotactic microstructure. EFFECT: improved method of polymerization, valuable properties of polymers. 10 cl, 1 tbl, 5 ex
