FIELD: chemistry.SUBSTANCE: invention relates to component of catalyst, intended for olefin polymerisation, containing magnesium, titanium, halogen and donor of electrons, wherein donor of electrons is represented by at least one of succinates, described by formula,and in said cussinates, described by formula (I), content of succinate, described by Fischer projection formula, represented by formula,is higher or equal to 76.1 wt % and lower than 100 wt%. In formula (I) and in formula (II) Rand R, which can be similar or different from each other, can stand for possessing linear chain (C~C)-alkyl group, possessing branched chain (C~C)-alkyl or cycloalkyl group, (C~C)-aryl or (C~C)-alkylaryl or -arylalkyl group; Rand R, which can be similar or different from each other, stand for halogen atom, possessing linear chain (C~C)-alkyl, possessing branched chain (C~C)-alkyl, (C~C)-cycloalkyl, (C~C)-aryl or (C~C)-alkylaryl or -arylalkyl group, and Rand Rcan be optionally bound with each other with formation of ring, and R, R, Rand Rcan optionally contain heteroatoms.EFFECT: obtaining catalyst with higher activity and stereospecificity.23 cl, 1 tbl |
