SPRAY DRYING-OBTAINED CATALYST COMPOSITIONS AND POLYMERISATION METHODS USING SAME Russian patent published in 2016 - IPC C08F4/70 C08F4/695 C08F10/02 

FIELD: chemistry.

SUBSTANCE: invention relates to a composition for polymerisation of olefins, produced by spray drying. Composition contains a containing transition metal catalytic component, described by the following formula: in which M denotes Fe[II], Fe[III], Co[I], Co[II], Co[III], Mn[I], Mn[II], Mn[III], Mn[IV], Ru[II], Ru[III] or Ru[IV]; X denotes an atom or a group of connected covalent or ionic bond with metal M; T denotes metal oxidation state; b denotes valency of atom or group X; and R₁-R₇ are all independently selected from a group comprising hydrogen, halogen, hydrocarbyl, substituted hydrocarbyl geterohydrocarbyl, substituted geterohydrocarbyl, aryl, substituted by hydrocarbyl aryl substituted by geterohydrocarbyl aryl, benzyl, substituted by hydrocarbyl benzyl, substituted geterohydrocarbyl benzyl and SiR′₃, where evey R′ is independently selected from a group comprising hydrogen, halogen, hydrocarbyll substituted hydrocarbyl, geterohydrocarbyl, substituted geterohydrocarbyl; and if any two or more of R₁-R₇ denote hydrocarbyl, substituted gidrokarbil, geterohydrocarbyl, substituted geterohydrocarbyl, aryl, substituted by hydrocarbyl aryl, substituted by geterohydrocarbyl aryl, benzyl, substituted by hydrocarbyl benzyl or substituted by geterohydrocarbyl benzyl, then two or more of them can be associated with formation of one or more cyclic substitutes; activator for produced by spray drying the catalytic composition; and a substrate for activator and produced by spray drying catalytic composition. Also disclosed is a method for polymerisation and a polymer product.

EFFECT: higher efficiency of a catalyst - transition metal complex.
