COMPONENTS OF CATALYSTS FOR POLYMERIZATION OF OLEFINS Russian patent published in 2004 - IPC

FIELD: organic chemistry, chemical technology, catalysts. SUBSTANCE: invention relates to components of catalysts used in polymerization of olefins of the formula: CH₂=CHR wherein R means hydrogen atom or hydrocarbon radical with 1-12 carbon atoms and comprising Mg, Ti, halogen atom, at least one 1,3-diester that forms complexes with anhydrous magnesium dichloride in the amount less 60 mmole per 100 g of MgCl₂ being without substitution reaction with TiCl₄, or reacting by less 50 mole% and at least one ester of mono- or polycarboxylic acid and 1,3-diesters are taken among compounds of the formula (II) wherein groups R^III are similar or different and represent hydrogen atom or C₁-C₁₈-hydrocarbon groups; groups R^IV are similar or different and have the same value as R^III with exception that they can't mean hydrogen atom; each of groups R^III-R^IV can comprise heteroatoms taken among halogen atoms, N, O, S and Si; radicals R^V are similar or different and taken among the group consisting of hydrogen, halogen atoms but Cl or F preferably, C₁-C₂₀-alkyl radical with direct or branched chain, C₃-C₂₀- cycloalkyl, C₆-C₂₀-aryl, C₇-C₂₀-alkaryl and C₇-C₂₀- aralkyl radicals; two or more radicals R^V can be bound to one another to form the condensed saturated or unsaturated cyclic structures optionally substituted with radicals R^VI taken among the group consisting of halogen atoms but Cl or F preferably, C₁-C₂₀-alkyl direct or branched radicals, C₃-C₂₀-cycloalkyl, C₆-C₂₀-aryl, C₇-C₂₀-alkaryl and C₇-C₂₀-aralkyl radicals. Indicated radicals R^V and R^VI comprise optionally one or more heteroatoms as substituents for carbon or hydrogen atom or for both. Also, invention claims a catalyst and a method for (co)polymerization. Indicated components of catalyst are able to provide preparing propylene polymers that owing to their high stability value against solubility in xylene show the broad range of stereoregularity. EFFECT: improved preparing method, valuable properties of catalyst. 23 cl, 4 tbl, 27 ex
