Description: Metathesis Polymerization Catalyst Solution and System for Preparing Crosslinked Polymers BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel metathesis polymerization catalyst solution, and to the combination of (i) a monomer solution A (solution A) comprising a metathesis polymerizable cychc olefin and a metathesis polymerization catalyst solution, and (ii) a monomer solution B (solution B) comprising a metathesis polymerizable cychc olefin and an alkylaluminum compound as an activator component of the metathesis polymerization catalyst system. Monomer solutions A and B are also called reactive solutions. The present invention also relates to a crosslinked polymer composition that is formed using the above described catalyst system. More specifically, this invention relates to (1) a metathesis polymerization catalyst solution formed with an ether compound and a phenol compound which act on W0C1 and or M0OCI3 during preparation of the metathesis polymerization catalyst solution, wherein a metathesis polymerizable cychc olefin is used as a solvent, (2) a combination of the catalyst solution described in (1) above and a metathesis polymerization catalyst activator solution comprising an alkylaluminum compound, (3) a combination of the metathesis polymerizable monomer solutions formed from the catalyst solution and the catalyst activator solution, respectively, and (4) a crosslinked polymer composition. This invention also provides a bul -polymerized crosslinked polymer composition formed by a reaction injection molding method having markedly improved physical properties and functions. Description of the Related Art Known methods in this field of art include a method of obtaining a crosslinked polymer composition which is formed by mixing (i) a monomer solution comprising a metathesis polymerizable cychc olefin and a catalyst component of a metathesis polymerization catalyst system (also called a double decomposition catalyst system), and (ii) a monomer solution comprising a metathesis polymerizable cychc olefin and an activator component, and by polymerizing and crosslinking this mixture in a mold into which it is injected as described in unexamined published Japanese AppHcation No. 28451/1991. This reaction injection molding method provides excellent advantages. Namely, (1) an easily available monomer can be used as a raw material; (2) monomer viscosity and injection molding pressure are low; (3) a shorter molding cycle is ensured by fast polymerization and crosslinking; (4) compositions such as a large- sized molded article can be formed with relative ease; and (5) the composition exhibits excellent balance between rigidity and impact strength. However, this crosslinked polymer composition has the following disadvantages. (1) Dicyclopentadiene is used as a metathesis polymerizable cychc olefin. When metathesis polymerization is performed using the catalyst described in unexamined pubhshed Japanese AppHcation No. 28451/1991, the heat resistance is as low as 100 °C, thereby hmiting the scope of its appHcation. (2) The scope of its application is also Hmited by a substantial reduction in impact strength when a bulky metathesis polymerizable cychc olefin such as tricyclopentadiene is subjected to metathesis polymerization (as described in examined Japanese Patent Pubhcation No. 62613/1993) in an effort to improve heat resistance. (3) Since the crosslinked polymer composition has a uniquely offensive odor, its appHcation is often Hmited to outdoor use. When used indoors and a question on the odor is raised, the crosshnked polymer composition must be covered by a coating to thereby prevent the unpleasant odor from proliferating. SUMMARY OF THE INVENTION The present inventors conducted studies to solve the above- described problems of the prior art, and especially with regard to a metathesis polymerization catalyst solution used in a method of obtaining a crossHnked polymer composition which is formed by (1) mixing a monomer solution A (solution A) comprising a metathesis polymerizable cychc olefin and a catalyst component of a metathesis polymerization catalyst system, and a monomer solution B (solution B) comprising a metathesis polymerizable cychc olefin and an alkylaluminum compound as an activator component of the metathesis polymerization catalyst system, and (2) polymerizing and crosslinking this mixture in a mold into which said mixture is injected. Namely, the present inventors discovered that cationic polymerization is prevented if an ether compound and a phenol compound are made to act on W0C1 and/or MoOC and a metathesis polymerizable cychc olefin is used as a solvent. This aUows for the use of a metathesis polymerizable cychc olefin which could not previously have been used as a solvent for catalyst preparation due to cationic polymerization caused by the catalyst. The inventors also discovered that the crossHnked polymer composition using this polymerization catalyst solution provides a substantial improvement in heat resistance with no reduction in impact strength. The present inventors further discovered that prevention of the cationic polymerization is more effective when a chain ether is added as the ether compound. The present inventors also discovered that a chain ether compound is preferably used as the ether compound which serves as a reaction velocity moderator when added to the metathesis polymerization catalyst activator solution. Furthermore, the present inventors discovered that use of the metathesis polymerizable cychc olefin alone in the presence of the ether compound as a solvent for preparing the metathesis polymerization catalyst solution ehminates the need for using a solvent which does not take part in the metathesis polymerization (e.g., toluene). This reduces the fumes and offensive odor produced during the molding operation due to use of a solvent which does not take part in the metathesis polymerization reaction (e.g., toluene). The offensive odor is different from that of the solvent itself which does not take part in the metathesis polymerization (e.g., toluene). The reason for this is not clear. However, it is considered that the presence of such a solvent promotes volatilization of the offensive odor from within the crossHnked polymer composition. The present invention has been achieved based on the above findings. More specifically, the present invention relates to the foUowing: 1.

DETAILED DESCRIPTION OF THE INVENTION The expression "the ether compound is made to act on W0C1 4 and/or MoOCl 3 " in the metathesis polymerization catalyst solution of the present invention means preparing a metathesis polymerization catalyst solution by adding WOCl and/or MoOCl 3 to a mixture of an ether compound and a metathesis polymerizable cychc olefin, or by adding a metathesis polymerizable cychc olefin after adding W0C1 4 and or M0OCL3 to the ether compound. The phenol compound improves catalyst activity and also modulates the reaction velocity. Making the phenol compound act on WOCLi and/or M0OCL3 means to add the phenol compound in any of the phases of preparing the metathesis polymerization catalyst solution of the present invention. For example, the phenol compound can be added to the mixture containing the WOCLi and or MoOCl 3 and ether compound; however, other methods may also be used. This action is considered to cause the ether compound to coordinate with the WOCI4 and or M0OCI3, or with the tungsten compound and/or molybdenum compound formed from reaction of the phenol compound and the W0C1 4 and/or M0OCL3 As used herein, the expression "the monomer solution A (solution A)" means a solution of a metathesis polymerizable cychc olefin and a catalyst component of the metathesis polymerization catalyst system which can be formed, for example, by adding a catalyst component of the metathesis polymerization catalyst system to a metathesis polymerizable cychc olefin, or by adding a metathesis catalyst solution containing a catalyst component to a metathesis polymerizable cychc olefin. As used herein, the expression "the monomer solution B (solution B)" means a solution of a metathesis polymerizable cychc olefin and an activator component of the metathesis polymerization system which can be formed, for example, by adding an activator component of the metathesis polymerization catalyst system to a metathesis polymerizable cychc olefin, or by adding a metathesis polymerization catalyst activator solution containing an activator component to a metathesis polymerizable cychc olefin. Cationic polymerization due to a reaction between the metathesis polymerizable cychc olefin monomer and the transition metal can be reduced by making the ether compound act on WOCLi and or MoOClβ. This provides a novel metathesis polymerization catalyst solution for preparing a crossHnked polymer, as weU as an olefin metathesis crosslinked polvmer composition featuring superior heat resistance as compared to those in the conventional art. Furthermore, because a metathesis polymerizable cychc olefin can be used in the presence of the ether compound as a solvent in preparing a metathesis polymerization catalyst solution to eHminate the need for using other solvents which do not take part in the metathesis polymerization, the olefin metathesis crossHnked polymer composition as a final product does not virtuaUy contain any inert (unreacted) solvents. This ehminates adverse effects on mechanical and physical properties including heat resistance, tensile and flexural strength when compared to a conventional crossHnked polymer containing unreacted solvents. Thus, the present invention provides a polymer having superb mechanical and physical properties. The metathesis polymerizable cychc olefin monomer used as a solvent in the metathesis polymerization catalyst solution according to the present invention is metathesis-polymerizable. Even if one of the metathesis polymerizable cychc olefin monomers is a sohd at normal temperatures, it can be used as a solvent if it is mixed with other metathesis polymerizable cychc olefin monomers or is made Hquid by addition of an ether compound. Illustrative examples of the metathesis polymerizable cychc olefin used as a solvent for the metathesis polymerization catalyst solution are dicyclopentadiene, tricyclopentadiene, cyclopentadiene- methylcyclopentadiene codimer, 5-ethyhdene norbornene, vinyl norbornene, norbornene, norbornadiene, 5-cyclohexenyl norbornene, l,4,5,8-dimethano- l,4,4a,5,6,7,8,8a-octahydronaphthalene, 1,4-methano- l,4,4a,5,6,7,8,8a-octahydronaphthalene, 6-ethyhdene- 1,4,5, 8-dimethano- l,4,4a,5,6,7,8,8a-octahydronaphthalene and ethylene-bis (5-norbornene). Combinations thereof can also be used. Especially, dicyclopentadiene, a mixture containing at least 50 mol% dicyclopentadiene, and a mixture containing at least 70 mol% dicyclopentadiene are preferred. Furthermore, a metathesis polymerizable cychc olefin comprising at least one of dicyclopentadiene, ethyhdene norbornene and tricyclopentadiene is preferred. The ether compound to prepare the metathesis polymerization catalyst solution in the present invention includes cychc ethers and chain ethers. The cychc ether includes tetrahydrofuran, tetrahydropyran and dioxane. The chain ether comprises ethers having an aryl or aralkyl group such as anisole, phenetole, phenyl ether, benzyl ether, phenylbenzyl ether, decabromo diphenyl ether and decachloro diphenyl ether, as weU as ethers having a vinyl group or an allyl group such as vinyl ether, allyl ether, methylvinyl ether, methylallyl ether, ethylvinyl ether and ethylallyl ether. In addition, the chain ether includes ethers represented by the general structural formula (1) below, where Ri is an alkylene chain having from 2 to 6 carbon atoms, and R 2 and R 3 each represents an alkyl group having from 1 to 8 carbon atoms. The hydrogen atoms of Ri, R 2 and R 3 may be substituted by one or more halogen atoms. R 2 and R 3 may be the same or different, n is an integer of from 0 through 40, denoting the number of repeating units. When n is 0, the compound represented by the general formula (1) is a monoether having one ether Hnkage within a molecule thereof, such as diisopropyl ether, dibutyl ether, amyl ether, isoamyl ether, methylethyl ether, methylpropyl ether, methylbutyl ether, methyhsobutyl ether, methylamyl ether, methylisoamyl ether, ethylpropyl ether, ethylbutyl ether, ethyHsobutyl ether, ethylamyl ether and ethyhsoamyl ether. When n is 1 to 40, the compound is a polyether having multiple ether linkages within a molecule thereof. Illustrative examples of the polyether include the dialkyl ether of alkylene glycol and/or polyalkylene glycol. Illustrative examples of the alkylene glycol include ethylene glycol, propylene glycol, 1,4-buta diol, 1,3-butandiol, 1,5-pentandiol, 1,6- hexandiol, 2,5-hexandiol and 2-chloro-l,3-propanediol. Those having from 2 to 6 carbon atoms are preferred. Specific examples of the polyalkylene glycol include diethylene glycol, triethylene glycol, tetraethylene glycol, dipropylene glycol, tripropylene glycol, tetrapropylene glycol, dibutylene glycol, tributylene glycol and similar glycols having a low degree of polymerization. Also included are polyethylene glycol and polypropylene glycol having a molecular weight of up to about 2,000 with about 4 to 40 repeating units where both terminals are alkylated. The aLkyl group forming the terminus of the dialkyl ether compound preferably has from 1 to 8 carbon atoms. Representative dialkyl ether compounds of the alkylene glycol and/or the polyalkylene glycol compound include ethylene glycol dimethyl ether, diethylene glycol dimethyl ether, triethylene glycol dimethyl ether, ethylene glycol diethyl ether, diethylene glycol diethyl ether, triethylene glycol diethyl ether, polyethylene glycol diethyl ether and polyethylene glycol dioctyl ether. Mixtures of these ether compounds can also be used. In the present invention, the ether compound to prepare the metathesis polymerization catalyst solution can be used in an amount of from 1 to 3 mols per mol of the WOCl 4 and/or M0OCI3. The amount of the metathesis polymerizable cychc olefin used as a solvent is not particularly Hmited so long as the WOCLi and or M0OCI3 can be uniformly dissolved or dispersed. Generally, the metathesis polymerizable cychc olefin as a solvent is used in an amount so that the concentration of the W0C1 4 and/or MoOCls is in the range of from 0.1 to 5.0 mols/Hter. Illustrative examples of the phenol compound that is used to enhance the activity of the catalyst according to the present invention and to modulate the reaction velocity include alkylphenol and 2,6-dihalo-4- alkylphenol (where the alkyl group has from 1 to 18 carbon atoms).

The reaction velocity can be reduced by using a phenol compound having a bulky substituent at the 2 and/or 6 position of the phenol compound. Furthermore, a mixture of two or more types of phenol compounds can be used. The phenol compound generates hydrogen chloride when it is made to act in the mixture containing the WOCl and/or M0OCI3 and the ether compound, for example, in preparing the metathesis polymerization catalyst solution of the present invention. This suggests that the phenol compound reacts with tungsten or molybdenum to form a phenoxy group. The substance formed when the ether compound acts on the WOCI4 and or M0OCI3 has improved solubility with respect to the metathesis polymerizable cychc olefin monomer such that additional phenol compound is not needed to make the catalyst soluble. Therefore, from the viewpoint of the reactivity of the catalyst, the phenol compound can be used in an amount of from more than 0 but less than or equal to 3 mols per mol of WOCl 4 and/or M0OCI3. Monomer solution B (solution B) contains an organic aluminum compound as an activator component of the metathesis polymerization catalyst system. An alkylaluminum compound, an alkylaluminum hahde compound and an aLkoxyaluminum compound are preferred. More specifically, useful examples of the organic aluminum compound include diethylaluminum chloride, ethylaluminum dichloride, triisobutylaluminum, trioctylaluminum, dioctylaluminum iodide, ethoxydiethyl aluminum, diethoxyethyl aluminum and ethoxyethyl aluminum chloride. A mixture of two or more types of these organic aluminum compounds can be used. The crosslinked polymer composition can be formed by mixing the above described solutions A and B and injecting them into a mold. However, when using the above-described solutions, polymerization may start at a very early phase and hardening occurs before sufficient amounts of the solutions are injected into the mold. In this case, a reaction velocity modifier can be added to the solution B containing an organic alkylaluminum compound. Preferably used as a reaction velocity moderator is an ether compound, especially a chain ether compound represented by the following general structural formula (1) below, where Ri is an alkylene chain having from 2 to 6 carbon atoms, and R2 and R 3 represent an alkyl group having from 1 to 8 carbon atoms. R 2 and J may be the same or different, n is an integer from 0 to 40, denoting the number of repeating units.

When n is 1 to 40, the compound is a polyether having multiple ether linkages within the molecule. Illustrative examples of the polyether include the dialkyl ether of alkylene glycol and/or polyalkylene glycol. Illustrative examples of the alkylene glycol include ethylene glycol, propylene glycol, 1,4-butandiol, 1,3-butandiol, 1,5-pentandiol, 1,6-hexandiol and 2,5-hexandiol. Those having from 2 to 6 carbon atoms are preferred. Specific examples of the polyalkylene glycol include diethylene glycol, triethylene glycol, tetraethylene glycol, dipropylene glycol, tripropylene glycol, tetrapropylene glycol, dibutylene glycol, tributylene glycol and similar glycols having a low degree of polymerization. Also included are polyethylene glycol and polypropylene glycol having a molecular weight of up to about 2,000 with about 4 to 40 repeating units where both terminals are alkylated.

When WOCLi is used as a catalyst component, for example, the molar ratio of the metathesis polymerizable monomer contained in monomer solutions A and B to the WOCLi is from 1,000 : 1 to 40,000 : 1, and preferably from 1,500 : 1 to 20,000 : 1. For the activator component, the molar ratio of the metathesis polymerizable monomer contained in monomer solutions A and B to the aluminum compound is from 100 : 1 to 20,000 : 1, and preferably from 200 : 1 to 10,000 : 1.

The composition of the above-described metathesis polymerizable cychc olefin monomer used as a raw material for the metathesis polymerization can be the same as or different from the metathesis polymerizable cycHc olefin monomer used as a solvent for preparing the metathesis polymerization catalyst solution. As a metathesis polymerizable cychc olefin monomer serving as a raw material for the metathesis polymerization, a metathesis polymerizable cycHc olefin having a polar group containing different types of elements such as oxygen, nitrogen and halogen elements can be used in the capacity of a co-monomer as needed.

When a monomer having a group which forms a Lewis base is used as a raw material for the metathesis polymerization, the monomer can also function as a modulator. Furthermore, an antioxidant is preferably added to the crossHnked polymer composition of the present invention. Thus, a phenol or amine based antioxidant is preferably added to the solutions A and/or B in advance. Illustrative examples of the antioxidant are 2,6-di- t-butylcresol, N, N'-ohphenyl-p-phenylenediamine and tetrakis [methylene (3,5-di-t-butyl-4-hydroxycinnamate)]methane. Also, other polymers can be added to the crossHnked polymer composition of the present invention whUe in the state of a monomer solution. For example, an elastomer can be added to enhance the impact strength of the crossHnked polymer composition and to control the viscosity of the solutions A and or B. An extensive range of elastomers can be used for this purpose such as styrene-butadiene-styrene block rubbers, styrene-isoprene-styrene block rubbers, polybutadiene, polyisoprene, butyl rubber, ethylene-propylene-diene terpolymer and nitrile rubber. Other additives include halogenated hydrocarbon and halogen compounds to enhance the reaction rate such as hexachloroxylene, a, a, α-trichlorotoluene, carbon tetrachloride, 1, 1, 1-trichloroethane, aUyl- chloride and benzylchloride. Furthermore, halogen compounds including siHcon, boron, sulfur and phosphorous are effective in enhancing reaction efficiency. The use of a reinforcement or filler as an additive is effective in improving the flexural modulus. These materials include glass fiber, mica, carbon black and woUastonite. The reinforcement or filler is often subjected to surface treatment with a so-caUed silane coupler. As discussed above, the crosslinked polymer composition is formed by simultaneous polymerization and molding. The molding method may comprise (1) a resin injection method where a premix comprising a catalyst and a monomer solution mixed in advance is poured into a mold; and (2) a RIM (reaction injection molding) method where the catalyst system is divided into two solutions A and B which collide and are mixed with each other in a mixing head, and then injected into the mold. In any case, the mold injection pressure can be kept comparatively low, and this aUows use of a less expensive mold. Furthermore, when polymerization begins in the mold, the temperature within the mold is increased by the exotherm, and the polymerization is complete in a short period of time. Unlike the case of polyurethane RIM, demolding is easy, and is usuaUy carried out without any releasing agent. Because an oxidated layer is formed on the surface, the crossHnked polymer composition provides exceUent adhesion to generaUy used paints such as epoxy and urethane paints. The present invention is described in greater detail by reference to the foUowing Examples. However, the present invention should not be construed as being Hmited thereto. In the foUowing Examples, the metathesis polymerization catalyst solution is caUed a "catalyst solution". EXAMPLES Catalyst Solution Preparation Example 1 150 g of dicyclopentadiene (hereinafter referred to as "DCPD") and 45.0 g (0.5 moles) of ethylene glycol dimethyl ether were placed into a one-hter flask and homogenized to prepare a solvent for a catalyst solution. Oxygen in this solution and oxygen in the flask were replaced with nitrogen by blowing nitrogen into the solution for preparing a catalyst solution. 85.5 g (0.25 moles) of WOCL crystal was graduaUy added to this system, and was uniformly dissolved into a mixture solution of DCPD and ethylene glycol dimethyl ether by stirring and mixing. When the WOC was added, the solution temperature and viscosity did not rise. Then, a solution was prepared by dissolving 55.0 g (0.25 moles) of nonylphenol into 55.0 g of DCPD to thereby reduce the viscosity of the nonylphenol. The resulting solution was added dropwise from the upper portion of the flask. After the addition, the contents were agitated at room temperature for 17 hours. DCPD was added so that the tungsten concentration was 0.5 mol per Hter in the final phase to provide a catalyst solution for polymerization. AU operations in Example 1 were conducted under a nitrogen atmosphere. Afterwards, this catalyst solution was found to be stable without the occurrence of cationic polymerization after being held at room temperature and under a nitrogen atmosphere for not less than one month. Example 2 A catalyst solution was prepared in the same manner as Example 1, except that WOCL was replaced by MoOC , and the ethylene glycol dimethyl ether was replaced by diethylene glycol dimethyl ether. Afterwards, this catalyst solution was found to be stable without the occurrence of cationic polymerization after being held at room temperature under a nitrogen atmosphere for not less than one month. Example 3 A catalyst solution was prepared in the same manner as Example 1, except that a mixture solution of a metathesis polymerizable cychc olefin comprising DCPD and ethyhdene norbornene mixed at a molar ratio of 90 to 10 and dibutyl ether was used instead of the mixture of DCPD and ethylene glycol dimethyl ether. Afterwards, this catalyst solution was found to be stable without the occurrence of cationic polymerization after being held at room temperature under a nitrogen atmosphere for not less than one month. Example 4 150 g of a metathesis polymerizable cychc olefin comprising DCPD and tricyclopentadiene mixed at a molar ratio of 90 to 10 and 45.0 g (0.5 moles) of ethylene glycol dimethyl ether were placed into a one-Hter flask, and homogenized to prepare a solvent for a catalyst solution. Oxygen in this solution and oxygen in the flask were replaced with nitrogen by blowing nitrogen into the solution for preparing a catalyst solution. 85.5 g (0.25 moles) of WOCL crystal was graduaUy added to this system and uniformly dissolved into a mixture solution of DCPD, tricyclopentadiene and ethylene glycol dimethyl ether by stirring and mixing. When the WOCL was added, the solution temperature and viscosity did not rise. Then, a solution was prepared by dissolving 51.5 g (0.25 moles) of t-octylphenol into 22.5 g (0.25 mol) of ethylene glycol dimethyl ether. The resulting solution was added dropwise from the upper portion of the flask. After the addition, the contents were agitated at room temperature for 17 hours. DCPD was then added so that the tungsten concentration was 0.5 mol per Hter in the final phase to obtain a catalyst solution for polymerization. AU of these operations were conducted under a nitrogen atmosphere. Afterwards, this catalyst solution was found to be stable without the occurrence of cationic polymerization after being held at room temperature under a nitrogen atmosphere for not less than one month. Example 5 A catalyst solution was prepared in the same manner as Example 1, except that the phenol compound was replaced by 2,6-dimethyl phenol. Afterwards, this catalyst solution was found to be stable without the occurrence of cationic polymerization after being held at room temperature under a nitrogen atmosphere for not less than one month. Example 6 A catalyst solution was prepared in the same manner as Example 1, except that the ether compound was replaced by diethylene glycol dimethyl ether, and the phenol compound was replaced by 2,6-diisopropyl phenol. Afterwards, this catalyst solution was found to be stable without the occurrence of cationic polymerization after being held at room temperature under a nitrogen atmosphere for not less than one month. Example 7 A catalyst solution was prepared in the same manner as Example 1, except that the ether compound was replaced by triethylene glycol dimethyl ether, and the phenol compound was replaced by 2,6- dibromononyl phenol. Afterwards, this catalyst solution was found to be stable without the occurrence of cationic polymerization after being held at room temperature under a nitrogen atmosphere for not less than one month. Example 8 A catalyst solution was prepared in the same manner as Example 1, except that the ether compound was replaced by diethylene glycol dimethyl ether, and the added amount of the nonylphenol compound was doubled. Afterwards, this catalyst solution was found to be stable without the occurrence of cationic polymerization after being held at room temperature under a nitrogen atmosphere for not less than one month. Example 9 A catalyst solution was prepared in the same manner as Example 1, except that the ether compound was replaced by tetrahydrofuran as a cychc ether. Afterwards, this catalyst solution was found to be stable without the occurrence of cationic polymerization after being held at room temperature under a nitrogen atmosphere for not less than one month. Comparative Example 1 A metathesis polymerizable cychc olefin comprising DCPD and ethyhdene norbornene mixed at a molar ratio of 90 to 10 was placed into a one-liter flask and used as a solvent. Oxygen in this solution and oxygen in the flask were replaced with nitrogen by blowing nitrogen into the solution for preparing a catalyst solution. An attempt was made to graduaUy add 85.5 g (0.25 moles) of WOCL crystal to this system. During the course of the addition, the temperature in the solution began to rise, so the crystal addition was not completed. Afterwards, the temperature continued to rise, and the substance inside the flask eventuaUy solidified. Thus, it was not possible to prepare a catalyst solution. Comparative Example 2 A catalyst solution was prepared in the same manner as Example 1, except that toluene was used in place of a metathesis polymerizable cychc olefin as a solvent. Afterwards, this catalyst solution was found to be stable without the occurrence of cationic polymerization after being held at room temperature under a nitrogen atmosphere for not less than one month. Table 1 summarizes the composition of the catalysts prepared in the above-mentioned Examples and Comparative Examples. Table 1 Components of the Catalyst System Example 10 (Preparation of Solution A) Solution A was prepared by adding the catalyst solution of Example 1 to a solution formed by adding 3 parts by weight of ethylene- polypropylene-ethyhdenenorbornene polymerized rubber having an ethylene content of 70 mol% and 2 parts by weight of Ethanox 702 made by Ethyl Corp. as an antioxidant, to a monomer mixture serving as a metathesis polymerization material comprising 97 parts by weight DCPD and 3 parts by weight ethyhdenenorbornene, so that the tungsten content was 0.01 mol per Hter. The viscosity of this solution was 300 cps at 30 °C. AU of these operations were performed under a nitrogen atmosphere. Afterwards, solution A was found to be stable without the occurrence of cationic polymerization after being held at room temperature under a nitrogen atmosphere for not less than one month. (Preparation of Solution B) Solution B was prepared by mixing a metathesis polymerization catalyst activator solution comprising triisobutylaluminum and diethylene glycol dimethyl ether mixed at a molar ratio of 100 to 50 with a monomer mixture formed by adding 3 parts by weight ethylene- polypropylene-ethyhdenenorbornene polymerized rubber having an ethylene content of 70 mol% to a monomer mixture serving as a metathesis polymerization material comprising 97 parts by weight DCPD and 3 parts by weight ethyhdenenorbornene, so that the aluminum content was 0.015 mol per Hter. AU of these operations were performed under a nitrogen atmosphere. The viscosity of this solution B was 300 cps at 30 °C. (Evaluation of Reactivity) 10 ml of each of solutions A and B of this Example controUed at 30 °C was measured out with a syringe, and the solutions A and B were injected into a 100 ml nitrogen-substituted glass vessel provided with an agitator to start polymerization. The time for the temperature to reach 100 °C from 30 °C due to heat generated by the polymerization was 42 seconds, and a maximum temperature of 194 °C was reached.

The results are shown in Table 2. It is clearly seen that the bulky substituents introduced at positions 2 and 6 of the phenol compound (2,6- diisopropyl phenol) were effective in controlling the reaction velocity. The amount of fumes released when the mold was opened was very smaU because an unreacted solvent was not present in the reaction system. There was Httle offensive odor at the molding site or from the molded plaque itself Afterwards, solution A was found to be stable without the occurrence of cationic polymerization after being held at room temperature under a nitrogen atmosphere for not less than one month. Example 16 Preparation of Solutions A and B, Evaluation of Reactivity and Molding and Physical Properties were carried out in the same manner as Example 10, except that the catalyst solution prepared in Example 7 was used. The results are shown in Table 2. It is clearly seen that the bulky substituents introduced at positions 2 and 6 of the phenol compound (2,6- dibromononyl phenol) were effective in controlling the reaction velocity.

The results are shown in Table 2. Although the same catalyst system was used, heat resistance was 110 °C which was not sufficient. This is because the molded plaque contained toluene as an unreacted solvent. When the mold was opened, a large amount of fumes was released because an unreacted solvent was present in the reaction system. There was a noticeably strong offensive odor at the molding site and also from the molded plaque itself. As shown in Tables 1 and 2, the present invention relates to a metathesis polymerization catalyst solution for preparing a crosslinked polymer composition. The crosslinked polymer composition is formed by mixing a monomer solution A (solution A) comprising a metathesis polymerizable cyclic olefin and a catalyst component of a metathesis polymerization catalyst system, and a monomer solution B (solution B) comprising a metathesis polymerizable cyclic olefin and an aliylaluminum compound as an activator component of the metathesis polymerization catalyst system, and by polymerizing and crosslinking the mixture in a mold into which it is injected. Cationic polymerization is prevented if an ether compound and a phenol compound are made to act on the W0C1 and/or M0OCI3, and a metathesis polymerized cyclic olefin is used as a solvent in preparing said metathesis polymerization catalyst solution. Thus, this invention allows for use of a metathesis polymerizable cyclic olefin which could not hitherto have been used as a solvent due to cationic polymerization caused by the catalyst. Also, unreacted solvents can be eliminated by using only the metathesis polymerizable cyclic olefin monomer as a solvent, to thereby reduce the amount of fumes and offensive odor generated at the molding site and from a molded article. Furthermore, the present inventors found that an ether compound is advantageously added as a reaction velocity modulator to the monomer solution B to thereby improve catalytic activity and provide a substantial improvement in heat resistance without reducing impact strength. The monomer solution A (solution A) containing a metathesis polymerizable cyclic olefin compound of the present invention has excellent handling properties as a metathesis polymerization material even after storage for a long period of time, without a reduction in reaction activity or increase in viscosity. While the invention has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that various changes and modifications can be made therein without departing form the spirit and scope thereof.
