FIELD: chemistry.SUBSTANCE: invention relates to solid hydrocarbon-insoluble component of catalyst for olefin polymerisation and to method of polymerisation in presence of said catalyst component. Catalyst component contains magnesium, titanium, halogen and additionally internal donor of electrons, which has structure [R-O-C(O)-O-]R, where Rindependently in each case represents aliphatic or aromatic hydrocarbon or substituted hydrocarbon group, containing from 1 to 20 carbon atoms; x equals 2-4; Rrepresents aliphatic or aromatic hydrocarbon or substituted hydrocarbon group, containing from 1 to 20 carbon atoms, on condition that in the shortest chain, connecting first R-O-C(O)-O- group and second R-O-C(O)-O- group, 2 atoms are contained.EFFECT: high efficiency of catalyst work and obtaining polymer with improved and various properties.14 cl, 4 tbl, 13 ex |
