  • Diene polymerisation
    Patent number: 8648000
    Abstract: Process for producing homopolymers or copolymers of conjugated dienes by contacting monomeric material including at least one conjugated diene with a catalyst system comprising (A) a first transition metal compound selected from Cr, Mo and W compounds, and a second transition metal compound selected from Fe, Co and Ni compounds, (B) a catalyst modifier and, optionally, (C) one or more catalyst activators.
    Type: Grant
    Filed: October 26, 2007
    Date of Patent: February 11, 2014
    Assignee: Ineos Commercial Services UK Limited
    Inventors: Juan Jose Chirinos-Colina, Vernon Charles Gibson, Grant Berent Jacobsen
  • Diene polymerisation
    Patent number: 8124698
    Abstract: Process for producing homopolymers or copolymers of conjugated dienes by contacting monomeric material having at least one conjugated diene with a catalyst system including two or more different transition metal compounds and optionally one or more activators. Preferred transition metal compounds are based on cobalt and chromium, especially complexes thereof having benzimidazole ligands.

  • Diene polymerisation
    Publication number: 20080293896
    Abstract: A process and catalyst for producing homopolymers or copolymers of conjugated dienes by polymerising the monomer with a catalyst system comprising (A) a first transition metal compound selected from Cr, Mo and W compounds, and a second transition metal compound selected from Fe Co and Ni compounds (B) a catalyst modifier (eg triphenyl phosphine) and optionally (C) one or more catalyst activators (eg MAO). The cis, trans and 1,2-vinyl microstructure of the produced diene polymer can be controlled.
