METHOD FOR ADDITION POLYMERISATION OF NORBORNENE Russian patent published in 2013 - IPC C08F32/08 C08F4/06 B01J37/00 B01J31/18 B01J31/22 

FIELD: chemistry.

SUBSTANCE: invention relates to a method for addition polymerisation of norbornene (NB) by reacting nickel (II) complexes, particularly bis(acetylacetonato)nickel (II) (Ni(acac)₂)), an organoaluminium compound, particularly triethyaluminium (AlEt₃,), a proton-donor compound, boron trifluoride etherate (BF₃·OEt₂) and stabilising components. The method is characterised by that the process employs methanol as (MeOH) as a proton-donor compound, stabilising components in form of trivalent phosphorus compounds, specifically triphenylphosphine (PPh₃), or tri-n-butylphosphine (P(n-Bu)₃), or tri-p-tolylphosphine (P(p-Tol)₃), or triisopropylphosphine (P(i-Pr)₃); the process is carried out in the medium of an organic solvent, e.g. toluene, with the following molar ratio of components: NB:Ni:P:Al:MeOH:B=2000:1:(0…4):3:10:(50…200), at room temperature.

EFFECT: method increases efficiency and reduces the cost of the process
