CATALYST COMPOSITION CONTAINING CHAIN SHUTTLE TRANSFER AGENT FOR FORMING ETHYLENE COPOLYMER Russian patent published in 2009 - IPC C08F295/00 C08F10/02 C08F4/64 

FIELD: chemistry.

SUBSTANCE: invention relates to compositions for ethylene polymerisation, to formation of homopolymer product having unique physical properties, to method for production of such homopolymers and produced polymeric products. Catalyst composition for preparing high molecular multiblock of homopolymer and containing mixture or resultant appeared due to compound of (A) the first catalyst of ethylene polymerisation, (B) the second catalyst of ethylene polymerisation, which is able to receive polymers differed by chemical and physical properties from polymer derived with the help of catalyst (A) in the equivalent conditions of polymerisation, at least one of the catalysts (A) or (B) is able to form branched polymer by growing chains or repeated incorporation of formed in situ ethylene polymer chains, and (C) agent of chain shuttle transfer where quantity of extractive multiblock of homopolymer when using is less than 10% from total mass of polymer of dialkyl ester or alkane.

EFFECT: preparation of multiblock of homopolymer with unique properties.
