It is also preferably represented by the above general formula (3). [(B) component] The component (B) is represented by the following general formula (2): R2 0 (Si R1 2 〇) m R2 (2) (wherein R1 is the same or different unsubstituted or substituted A monovalent hydrocarbon group, m is a positive number of from 1 to 50; R2 is an alkyl group or a hydrogen atom; an organic polyoxane or an organic decane, or a mixture thereof, having an alkoxy group or a hydroxyl group at the terminal of the molecular chain. The component (B) is treated as a treatment agent for cerium-enhanced cerium oxide or a dispersing agent. As shown in the general formula, R1 is the same or different, and the undesired or substituted carbon number is 1 to 12 More preferably, it is a monovalent hydrocarbon group having 1 to 8 carbon atoms. Examples of the monovalent hydroxyl group represented by R1 include an alkyl group such as a methyl group, an ethyl 'propyl group, a butyl group, a cycloalkyl group such as a cyclohexyl group. When the amount of the component (A) exceeds 100 parts by mass, the processability of the obtained polyoxyethylene rubber composition is lowered, and the component (C) is further reduced in the amount of the component (A). When the amount is less than 5 parts by mass based on 100 parts by mass of the component (A), the cured product obtained by curing the polyoxyethylene rubber composition does not have sufficient mechanical strength such as tensile strength and tear strength. [(D) (Component) The component (D) is a curing agent for curing a composition (basic composition) containing the above components (A) to (C). Examples of the curing agent include organic peroxides and addition crosslinking agents. A combination of a diene polyoxyalkylene oxide and a hydroformylation catalyst.

Di-t-butyl hexane, t-butyl benzoate peroxide, dicumyl peroxide, cumene peroxide-t-butyl, and the like. Among them, the atmospheric pressure hot gas is preferably used as a thiol-based organic peroxide such as phenylhydrazine peroxide, p-methylphenylhydrazine peroxide or o-methylphenylhydrazine peroxide. These oxides may be used singly or in combination of two or more. The amount of the organic peroxide to be added is 0.1 to 10 parts by mass, preferably 0.3 to 5 parts by mass, per part by mass of the organopolysiloxane of the component (A). Crosslinking in this range can be sufficiently carried out, and the rate of hardening can be increased by the amount added. By adding these organic peroxides to the basic composition to heat-harden, the polyoxyxene rubber can be easily obtained. When the hardener is a combination of an addition crosslinking agent (organohydrogen diene polyoxyalkylene) and hydrogen-15-(11) (11) 1356838 formazanation catalyst, the organopolyoxane of component (A) is selected to have 2 alkenyl people. The organohydrogen diene polyoxane may, for example, have two or more hydrogen atoms bonded to a perylene peroxide atom in the molecule. Examples of the hydroformylation catalyst include the addition amount of a ruthenium organohydrogen diene polyoxane such as a platinum compound or a ruthenium compound, and the number of hydrogen atoms bonded to the ruthenium atom in the organohydrogen diene polysiloxane. The ratio of the number of alkenyl groups in the component (A) (S i H / S i -alkenyl) is 〇. 5 to 5, and the ideal amount is 〇. 7 〜2. Further, the amount of the hydroformylation catalyst to be added is 0.1 to 2000 ppm, preferably 1 to 1000 ppm, more preferably 5 to 500 p p m, based on the organic polyoxo of the component (A).
