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

Abstract RU 2487895 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method for addition polymerisation of norbornene by using catalysts based on zero-valent nickel, an proton-donor compound (HA) and BF₃OEt₂. The method is characterised by that the proton-donor compound used in the process is methanol (MeOH), or acetylacetone (acacH), or fluoroboric acid etherate (HBF₄·OEt₂), the process being carried out in the medium of an organic solvent, for example, toluene, with molar ratio of boron to nickel B:Ni=400:1 and the ratio HA/Ni=9.

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