FIELD: chemistry.
SUBSTANCE: disclosed are catalytic compositions for polymerisation and methods of producing said compositions. Described is a catalyst composition containing at least one polymerisation catalyst on a substrate, wherein said catalyst composition is modified with at least one fatty amine, wherein said fatty amine contains less than 2 % by weight of fine inorganic material, wherein said at least one fatty amine is of formula: (R1)xN(R2OH)y, where R1 is a hydrocarbon radical containing from 8 to 40 carbon atoms; R2 is a hydrocarbylene biradical having 1 to 8 carbon atoms; and x takes value 1 or 2 and x + y = 3; and wherein said catalyst on a substrate contains one or more metallocene compounds selected from: (pentamethylcyclopentadienyl)(propylcyclopentadienyl)MX2, (tetramethylcyclopentadienyl)(propylcyclopentadienyl)MX2, (tetramethylcyclopentadienyl)(butylcyclopentadienyl)MX2, Me2Si(indenyl)2MX2, Me2Si(tetrahydroindenyl)2MX2, (n-propylcyclopentadienyl) 2MX2, (n-butylcyclopentadienyl) 2MX2, (1-methyl-3-butylcyclopentadienyl)2MX2, (propylcyclopentadienyl)(tetramethylcyclopentadienyl)MX2, (butylcyclopentadienyl)2MX2, and (propylcyclopentadienyl)2MX2, where M is Zr or Hf and X is selected from F, Cl, Br, I, Me, benzyl, CH2SiMe3 and C1-C5 alkyls or alkenyls.
EFFECT: technical result is creation of catalytic compositions for polymerisation of olefins, capable of continuous action in method of polymerisation at increased operation of reactor, improved efficiency.
