HOMOGENOUS CATALYTIC SYSTEM FOR SYNTHESIS OF COPOLYMERS OF ETHYLENE WITH PROPYLENE AND HIGHER α-OLEFINS AND ALSO PROPYLENE WITH HIGHER α-OLEFINS, METHOD OF PRODUCING COPOLYMERS OF ETHYLENE WITH PROPYLENE AND HIGHER α-OLEFINS AND ALSO PROPYLENE WITH HIGHER α-OLEFINS Russian patent published in 2005 - IPC

FIELD: polymer production.

SUBSTANCE: invention provides homogenous catalytic system for synthesis of copolymers and terpolymers of olefinic monomers, which system contains dialkyl bridge-type bis(indenyl)metallocene complexes with group IVB metals and trialkylaluminum at Al-to-metal ratio between 50 and 500. Catalytic system enables carrying out polymerization process at rates significantly exceeding ethylene or propylene homopolymerization rate.

EFFECT: significantly accelerated copolymerization process and achieved fractional and compositional homogeneity of ethylene/α-olefin and propylene/α-olefin copolymers.
