[0259] Hereinafter, although an Example demonstrates this invention, this invention is not limited at all by these Examples. In addition, "part" and "%" mean "part by weight" and "% by weight" unless otherwise indicated.
[0260] First, the measurement method of each physical property value and the evaluation method of a physical property are demonstrated.
[0261] (1) Molecular weight:
[0262] Using a Gel Permeation Chromatography (GPC) device (Model 150C) manufactured by WATERS Corporation equipped with an H-type column manufactured by TOSOH, under the conditions of o-dichlorobenzene solvent and 120°C, the weight in terms of standard polystyrene was measured. Average molecular weight (Mw) and number average molecular weight (Mn).
[0263] (2) Glass transition temperature (Tg):
[0264] Using a differential scanning calorimeter (DSC6200) manufactured by Seiko Instruments, the measurement was performed at a rate of temperature increase: 20° C. per minute, under a nitrogen ...
Synthetic example 1
[0273] The 8-methyl-8-methoxycarbonyltetracyclo[4.4.0.1 shown in the following formula (2) 2,5 .1 7,10 ] 100 parts of dode-3-ene (hereinafter also referred to as "DNM"), 18 parts of 1-hexene (molecular weight modifier), and 300 parts of toluene (solvent for ring-opening polymerization reaction) were charged to the nitrogen-substituted reaction In a container, the solution was heated to 80°C. Next, 0.2 parts of a toluene solution (0.6 mol / L) of triethylaluminum as a polymerization catalyst and 0.9 parts of a toluene solution (concentration 0.025 mol / L) of methanol-modified tungsten hexachloride were added to the solution in the reaction vessel. The ring-opening polymerization reaction was performed by heating and stirring the solution at 80° C. for 3 hours to obtain a ring-opening polymer solution. The polymerization conversion rate of this polymerization reaction was 97%.

[0275] 1000 parts of the ring-opening polymer solution obtained in this way are packed in...
Synthetic example 2
[0278] Sufficiently carry out drying, and in the 1L stainless steel reaction vessel that is replaced with nitrogen, the water content of 6ppm dehydrated cyclohexane 420.4g, p-xylene 180.2g, 5-trimethoxysilyl-bicyclo[2.2. 1] 48.75 mmol (10.43 g) of hept-2-ene, 1425 mmol (134.1 g) of bicyclo[2.2.1] hept-2-ene, and charged with gaseous ethylene so that the internal pressure of the reactor reached 0.1 MPa.
[0279] The reactor was heated to 75°C, and 0.003 milligram atoms of 2-ethylhexanoic acid palladium (as Pd atom) and 0.0015 mmol of tricyclohexylphosphine were reacted in 10 ml of toluene at 25° C. for 1 hour as a catalyst component to obtain a solution. The entire amount of the obtained solution and 0.00315 mmol of triphenylcarbenium pentafluorophenylborate were added in this order to start polymerization.
[0280] 90 minutes after the start of polymerization, 11.25 mmol (2.41 g) of 5-trimethoxysilyl-bicyclo [2.2.1] hept-2-ene was added, and then 7.5 mmol (1.61 g), 3.75 mmol (...
