FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing olefin/diene copolymers on a homogeneous metallocene catalyst system. Described is a method of producing copolymers of monomers by polymerisation of olefins or a mixture of olefins and linear or cyclic dienes in the presence of a homogeneous catalyst system. The catalyst system consists of dialkyl bridged bis-indenyl metallocene complexes of group IVB metals and aluminium trialkyls.
EFFECT: formation of copolymers with a controlled composition, the lowest compositional and fractional non-uniformity and preventing simultaneous formation of homopolymers.
