The cyclic olefin resin of the present invention 'is 8-methyl-8-methoxycarbonyltetracyclo[4.4.0.12, 5.17,1〇]-3-dodecene and bicyclo[2.2.1]g 2-ene (norbornene) or 8-methyl-8-methoxycarbonyltetracyclo[4.4_0.12, 5.17,1()]-3-dodecene and tricyclo[4.3.0.12, 5] A copolymer of hydrazine-3,7-diene (dicyclopentadiene) is particularly preferred. In the present invention, the copolymerization ratio of the 'cyclic olefin monomer (the compound represented by the formula (Γ)) and the cyclic olefin monomer (the compound represented by the formula (II)) is defined as 1 in total. In the case of 〇〇 by weight, it is generally desired that the cyclic hydrocarbon-based monomer (II,) is 0 to 40 parts by weight, preferably in the range of 〇 30 parts by weight. When the copolymerization ratio of the cyclic olefin monomer (yttrium) is more than 30 parts by weight, heat stability can be lowered by lowering the glass transition temperature and lowering the phase difference or size, and the like, and less than 3 parts by weight. The slidability and phase difference expression of the molded body, film or sheet may be lowered. In the present invention, the above-mentioned cyclic olefin monomers (I,) and (Π') may be used in a small amount in the range of not impairing the object of the present invention, or may be copolymerized in other amounts. Other monomer as a copolymerization raw material monomer The cyclic olefin resin according to the present invention may contain structural units other than the structural unit represented by the above formulas (1) and (11). The related structural unit ' can be obtained by using a cycloolefin monomer such as cyclobutene, cyclopentene, cycloheptene or cyclooctene, and the above cyclic olefin monomer (I') and (Π' Formed by ring-opening copolymerization together; in addition, by polybutadiene, polyisoprene, styrene-butadiene copolymer, ethylene-nonconjugated diene copolymer, poly In the presence of a polymer or the like in the main chain of norbornene or the like having an olefinic unsaturated bond, the above cyclic olefin monomers (Γ) and (11,) are subjected to ring opening. Formed by polymerization. However, in the present invention, it is preferred to carry out copolymerization using only the cyclic olefin monomers (I,) and (U,), that is, the cyclic olefin resin of the present invention, in addition to the above formula (I) and In addition to the structural unit represented by the above, other structural units may be provided within the scope of the object of the present invention, but structural units other than the structural units represented by the above formulas (I) and (π) are not provided. Preferably. A ring-opening copolymer having only a ring-opening copolymerization of each cyclic olefin monomer has an olefinic unsaturated bond in its molecule, and the related olefinic unsaturated bond is caused by problems such as heat-resistant coloring. Hydrogenation is preferred, but the related hydrogenation reaction is also suitable for use in conventional methods. Further, when tricyclo[4.3.0.12'5]癸-3,7-diene (dicyclopentadiene) is used as the cyclic olefin monomer (ΙΓ), the intramolecular host of the ring-opening copolymer The chain structure, in addition to the side chain structure, also has an olefinic unsaturated bond, which is preferably hydrogenated for the same reason, and the related hydrogenation reaction is also suitable for use in a conventional method. For example, a catalyst, a solvent, a temperature condition, etc. described in the Unexamined-Japanese-Patent No. 1-2. The ring-opening polymerization reaction and the hydrogenation reaction are carried out. The hydrogenation ratio of the olefinic unsaturated bond is usually desirably 8 〇 mol% or more, preferably 90 mol% or more, more preferably 95 mol% or more. Further, the hydrogenation reaction in the present invention, as described above, means a reaction with an olefinic unsaturated bond in the molecule, and the cyclic olefin-based resin of the present invention has an aromatic group because the related aromatic group is The optical characteristics such as the refractive index or the heat resistance of -23-200918969 are advantageous, so that it is not necessarily required to be hydrogenated. The molecular weight of the cyclic olefin resin according to the present invention is a polystyrene-equivalent number average molecular weight (?η) measured by gel permeation chromatography (GPC), and is usually desired to be 3χ103 to 5χ105, preferably 5χ103 to 3xl. 〇5, more preferably 1 XI 04 to 2xl 05, in addition, the polystyrene-equivalent weight average molecular weight (Mw)' is usually 5χ103~1χ106', preferably ΙχΙΟ4~5χ105, more preferably 2χ1〇4~4χ105. . When the molecular weight is too small, the strength of the obtained film may be low, and the phase difference expression during drawing processing may be lowered. On the other hand, when the molecular weight is too large, the solution viscosity may become too high and the copolymer of the present invention may be too high. Productivity or processability deteriorates. Further, the molecular weight distribution (Mw/Mn) of the cyclic olefin resin according to the present invention is usually desirably 1.5 to 10, preferably 2 to 7, more preferably 2 to 5.

Under the circumstance, it can be stably maintained, and it is excellent in adhesion and adhesion to other materials. Therefore, peeling or the like does not occur during use, and compatibility with additives such as antioxidants is excellent.

When the saturated water absorption rate is less than 5% by weight, the adhesion and adhesion of the obtained film system to other materials are low, and peeling tends to occur during use. -24-200918969 In addition, antioxidants and the like The amount of additives added is limited. On the other hand, when the saturated water absorption exceeds 1% by weight, it is easy to cause a change in optical characteristics or a dimensional change due to water absorption. Among them, the saturated water absorption rate is calculated based on ASTM D570' by measuring the weight gain after immersion in water at 23 ° C for 1 week.

The resulting change in optical characteristics becomes large. On the other hand, when the Tg exceeds 200 °C, the processing temperature at the time of stretching processing becomes too high, and the copolymer of the present invention is thermally deteriorated. Here, the Tg of the cyclic olefin resin is a differential scanning calorimeter (DSC), and the maximum peak temperature of the obtained differential differential scanning calorimetry curve is measured at a temperature increase rate of 20 ° C / min in a nitrogen atmosphere. (point A) and the maximum peak temperature from _20 °C (point B) are plotted on the differential scanning heat curve, and the intersection of the wiring on the base line starting from point B and the wiring starting from point A is calculated. • Polymeric catalyst The catalyst used for the production of the cyclic olefin resin according to the present invention is preferably, for example, a catalyst described in Olefin Metathesis and Metathesis Polymerization (K.J.
