METHOD FOR PREPARING CATALYST FOR POLYMERIZATION OF NORBORNENE Russian patent published in 2008 - IPC C08F32/08 B01J23/44 C08F4/26 

FIELD: catalysts, chemical technology.

SUBSTANCE: invention relates to a method for preparing a catalyst used in additive polymerization of norbornene to polynorbornenes. Invention describes a method for preparing a catalyst for additive polymerization of norbornene involving interaction of palladium (II) compound with boron trifluoride etherate in toluene medium as a solvent. Components are mixed in the following order: palladium compound solution is added to norbornene solution in organic solvent followed by addition of boron trifluoride etherate. Optimal conditions for the process are the following: the molar ratio boron to palladium, B : Pd = (5-1):(60-1), temperature 15-60°C. Invention provides enhancing effectiveness of the polymerization process. Synthesized compounds are used in producing cover in electronics, television-communication materials, optical lens, substrates for plastic displays, photoresistors for producing chips and displays, dielectrics for semiconductors.

EFFECT: improved method of synthesis.
