FIELD: polymer production.

SUBSTANCE: invention relates to supported catalytic compositions, methods for preparing such compositions, and polymer preparation processes using these compositions. In particular, invention provides supported catalytic composition including interaction product of: (i) catalyst precursor composition comprising product of reaction of magnesium halide, an ether, electronodonor compound, in particular linear or branched aliphatic C₁-C₂₅-alcohol, and transition metal compound, in particular compound of group IV element; (ii) porous inert carrier; and (iii) cocatalytic composition; wherein supported catalytic composition contains less than 1% electronodonor compounds other than those including linear or branched aliphatic or aromatic alcohol having from 1 to 25 carbon atoms and wherein molar ratio of electronodonor compound to magnesium is less than or equal to 1.9. Described are also method of preparing supported catalytic composition, method of preparing polymer comprising reaction of at least one olefin monomer in presence of above-mentioned supported catalytic composition. Described are also supported catalyst precursor composition, supported catalytic composition, method of preparing supported catalytic composition, and method of preparing polymer comprising reaction of at least one olefin monomer in presence of supported catalytic composition, and supported catalyst precursor composition.

EFFECT: increased catalytic activity and enabled preparation of polymer for films at lower partial pressure of ethylene.
