FIELD: biotechnology.
SUBSTANCE: invention relates to the production of additive copolymers of norbornene and its derivatives under the action of catalytic systems based on cationic palladium complexes and borontrifluoride etherate. Use of a catalyst containing a cationic complex (acetylacetonate) bis (triphenylphosphine) palladium tetrafluoroborate of the general formula [(acac)Pd(PPh3)2]BF4 for carrying out the additive copolymerization of norbornene with 5-methoxycarbonylnorbornene by reaction in an organic solvent medium. As cocatalyst, borontrifluoride etherate of general formula BF3⋅OEt2 is used. Process is carried out at a molar ratio of boron to palladium, [BF3⋅OEt2]0:[Pd]0 = 20:1 in an organic solvent: mixtures of methylene chloride and toluene.
EFFECT: technical result is the expansion of the arsenal of the copolymers obtained.
