Then, 500 ml of a 1.0 mol / L hydrochloric acid aqueous solution was added to the reaction vessel, and the mixture was stirred at 50 ° C. for 1 hour at 600 rpm. After separating the oil layer and the aqueous layer, the oil layer was added to a beaker containing about 3 times the volume of acetone under stirring to precipitate a copolymer, and the precipitated copolymer was separated from the filtrate by filtration. When the obtained polymer containing the solvent was dried under reduced pressure at 130 ° C. for 10 hours, a white powdery ethylene / tetracyclolodecene / undecylene acid copolymer (cyclic olefin copolymer containing a polar group (cyclic olefin copolymer). A-1)) 3.79 g was obtained. [0138] [Table 1] [0139] [Production Example 2] 　APL6015T (manufactured by Mitsui Chemicals, Inc.), 1.5 parts by mass of maleic anhydride (manufactured by Wako Pure Chemical Industries, Ltd.) and t-butylperoxybenzoate (manufactured by Nippon Oil & Fats Co., Ltd., trade name Perbutyl Z) A solution in which 1.5 parts by mass was dissolved in acetone was blended. Then, using a twin-screw kneader (manufactured by Technobel Co., Ltd., KZW15), melt modification was performed at a resin temperature of 250 ° C., a screw rotation speed of 200 rpm, and a discharge rate of 25 g / min. Upon extrusion, the radical initiator, solvent and unreacted maleic anhydride were evacuated. The extruded molten strand was pelletized after cooling to obtain a cyclic olefin copolymer (A-2) containing a polar group. [0140] Surface-modified zirconia surface-modified 　with butyric acid, lauric acid, palmitic acid, and dodecyl phosphate was produced by the following method. 　In a 200 mL eggplant flask set with a stirrer chip, take various hydrophobized surface modifiers in an amount corresponding to 23% by mass with respect to the zirconia to be treated, and use 42 mL of toluene as a water-insoluble organic solvent and an amphoteric organic solvent. To a certain methanol (30 mL) was added, 3 mL of a zirconia fine water dispersion (zirconia content: 30% by mass) was added and mixed. As the zirconia fine particle aqueous dispersion, Sakai Chemical Industry Co., Ltd. (SZR-W) was used. In the obtained mixed solution, toluene and water, which are water-insoluble organic solvents, are dissolved in methanol, which is an amphoteric organic solvent, to form a uniform liquid phase, and white turbidity, which is considered to be caused by zirconia fine particles, is generated. rice field. [0141] 　The mixture obtained above was stirred at room temperature for 1 hour, and then the dispersion medium was evaporated and removed by a rotary evaporator until the amount became about 3 to 5 mL. Evaporation and removal of the dispersion medium was carried out by reducing the pressure of the atmosphere to such a pressure that bumping in the liquid phase did not occur while keeping the mixed solution at room temperature. [0142] 　The mixed solution remaining in the eggplant flask after the first evaporation and removal of the dispersion medium had cloudiness, and the liquid phase was separated into two phases. Further, 30 mL of methanol and 42 mL of toluene were added to the mixed solution to make a cloudy dispersion having no interface again, and the operation of evaporation was performed again until the amount became about 3 to 5 mL. By repeating this operation approximately several times, the dispersion liquid could be changed from a cloudy state to a colorless and transparent state depending on the type and amount of the surface modifier used, and the remaining liquid phase could be made a single phase. In this example, the mixed solvent of water / methanol / toluene was replaced with a solvent containing only toluene to obtain a toluene dispersion of zirconia fine particles by 5 to 6 operations. 　Toluene was removed from the toluene dispersion of zirconia fine particles by evaporation and then vacuum dried at 25 ° C. for 24 hours to obtain white solid zirconia fine particles. The obtained zirconia fine particles were redispersed in toluene, and the particle size was measured by dynamic light scattering (DLS). The average particle size of the lauric acid-modified zirconia fine particles was 18.4 nm. [0143] A 　cyclic olefin polymer / zirconia nanoparticle composite film was prepared by the following method. In addition, various physical properties were measured or evaluated by the following methods. The results obtained are shown in Table 2. [Preparation of Cyclic Olefin Polymer / Zirconia Nanoparticle Composite Film] 　Cyclic olefin polymers A-1 and A-2 synthesized in Production Examples 1 and 2 and APL6509T manufactured by Mitsui Chemicals, Inc. (containing polar groups). Each of the cyclic olefin-based copolymers A-3) was dissolved in cyclohexane to prepare 5% by mass solutions. Then, a 5% by mass cyclohexane solution prepared by using the surface-modified zirconia surface-modified with butanoic acid, lauric acid, palmitic acid, and dodecylphosphate obtained by the above method was added to the polymer with zirconia nanoparticles. The mixture was added so as to have the ratio shown in Table 2, and the mixture was stirred with a magnetic stirrer at room temperature for 1 hour, allowed to flow on a glass plate, and bar-coated. After drying at 25 ° C. for 24 hours, the solvent was removed by vacuum drying at 80 ° C. for 15 hours to obtain a cyclic olefin polymer / zirconia nanoparticle composite film having a film thickness of 100 μm. [0144] [Total light transmittance] The 　total light transmittance was measured based on JIS K-7105 using a double beam type haze computer HZ-2 manufactured by Suga Test Instruments Co., Ltd., and evaluated according to the following criteria. 　Evaluation of total light transmittance 　◎: 90% or more 　○: 80% or more and less than 90% 　×: less than 80% [0145] [Glass transition temperature Tg (° C.)] Measured under 　an N 2 (nitrogen) atmosphere using DSC-6220 manufactured by Shimadzu Science Co., Ltd. The temperature was raised from room temperature to 200 ° C. at a heating rate of 10 ° C./min and then held for 5 minutes, and then the temperature was lowered to −20 ° C. at a temperature lowering rate of 10 ° C./min and then held for 5 minutes. Then, the glass transition temperature (Tg) of the polar group-containing cyclic olefin copolymer was determined from the heat absorption curve when the temperature was raised to 200 ° C. at a temperature rising rate of 10 ° C./min. [0146] [Refractive index] 　The refractive index (nD) at a wavelength of 589 nm was measured using a refractive index / film thickness measuring device (Prism Coupler Model 2010 / M manufactured by Metricon Co., Ltd.). [0147] [Evaluation of Solvent Resistance (Toluene)] 　0.3 g of the cyclic olefin polymer / zirconia nanoparticle composite film having a thickness of 100 μm obtained in Examples and Comparative Examples was placed in a flask and weighed (Y (Y). g)), toluene was added so as to form a 1% by mass solution, and the mixture was immersed at 25 ° C. for 24 hours. The insoluble matter was captured by filtering with a membrane filter (pore diameter 10 μm), dried at 25 ° C. for 48 hours, and then the mass (Z (g)) of the insoluble matter was measured. The insoluble fraction was calculated according to the following formula and evaluated according to the following criteria. 　Insoluble fraction (mass%) = (Z / Y) × 100 　Evaluation of insoluble fraction (mass%) 　○: Insoluble fraction ≥ Zirconia content (mass%) 　×: Insoluble fraction
