FIELD: chemistry.
SUBSTANCE: claimed invention relates to catalyst for olefin polymerisation, in particular, to catalyst which contains compounds of silicon ethers with novel structure, as well as to application of claimed catalyst in olefin polymerisation, and in particular, in propylene polymerisation. Described is catalyst for olefin polymerisation, containing reaction product, consisting of the following components: (A) hard titanium-containing catalytic component including magnesium, titanium and halogen as obligatory components; (B) catalytic component containing organic aluminium compound; (C) catalytic component containing compound of silicon ether, where said compound of silicon ether is represented by general formula: 
, groups R1-R12 and A are determined in description of claimed invention. Also described is application of catalyst for polymerisation of olefins with formula CH2=CHR, in which group R represents hydrogen or C1-C6 alkyl or aryl, or for copolymerisation of said olefins with α-olefin co-monomer which contains from 2 to 20 carbon atoms. Also described is method of olefin polymerisation including bringing into contact olefin with formula CH2=CHR, in which R is hydrogen or C1-C6 alkyl or aryl. Also described is method of propylene polymerisation, including bringing into contact propylene.
EFFECT: application of catalyst, containing described above product, for olefin polymerisation.
