CATALYST COMPOSITION, METHOD FOR MORPHOLOGY CONTROLLED POLYMERISATION OF OLEFINS AND POLYMER COMPOSITION Russian patent published in 2012 - IPC C08F4/50 C08F4/64 C08F10/00 C08L23/02 

FIELD: chemistry.

SUBSTANCE: composition contains a catalytic compound, an activator, optional support and liquid solvent, and a hydroxy carboxylate addition salt of a metal , where R^f denotes hydrogen, halogen or C_1-6 alkyl. The polymer composition contains a product of polymerisation of one or more olefin monomers in the presence of a catalyst composition, wherein the hydroxy carboxylate addition salt of a metal is or , where R^c denotes hydrogen, halogen or C_1-6 alkyl.

EFFECT: possibility of implementing a continuous technique with improved operational capabilities of the reactor while obtaining novel improved polymers, reduced tendency for contamination, formation of a polymer film and longer operating life.
