5-Butylnorbornene (9.8 kg), 5-norbornene-2-carboxylic acid butyl ester (8.5 kg) and 5-norbornene-2-carboxylic acid methyl ester (16.7 kg) were added to a reactor at room temperature. Toluene (26.3 kg) was added to the reactor. Air inside the reactor was replaced by nitrogen and the reactor was heated to 90° C. Palladium diacetate (6.2 g), dimethyl aniliniumtetrakis (pentafluorophenyl)borate (44.1 g) and tricylcohexylphosphine (7.7 g) dissolved in dichloromethyl were added to the reactor. Reaction was performed for 18 hours while stirring to obtain a tricopolymer solution comprising 30 mol % of 5-butylnorbornene, 20 mol % of 5-norbornene-2-carboxylic acid butyl ester and 50 mol % of 5-norbornene-2-carboxylic acid methyl ester monomers. 43.9 kg of toluene was added to dilute the solution.
