    摘要： A seal ring seals operating oil hermetically and is attached to an annular seal ring groove provided on an outer circumference of a shaft member. The seal ring comprises fluororesin, metal powder having a hardness equal to or more than that of any of a side surface of the seal ring groove serving as a sliding partner and an inner circumferential surface of a housing engaged relatively rotatable with the outer circumference of the shaft member, and modified fluororesin formed by irradiating an ionizing radiation in a range from 1 kGy to 10 MGy inclusive in a state of being heated up to a melting point thereof or higher under an inert gas atmosphere with an oxygen partial pressure of 1.33 kPa or less.

    摘要： A fluororesin heated at a temperature at or above the melting point of the resin is exposed in an inert gas atmosphere having an oxygen concentration of not more than 10 Torr to an ionizing radiation at a radiation dose of 0.1 kGy to 10 MGy to prepare a crosslinked fluororesin. The crosslinked fluororesin is exposed to an ionizing radiation at a radiation dose of 10 kGy to 5 MGy, and is then brought into contact with a functional group-containing organic compound to cause a graft reaction. By virtue of this constitution, a modified fluororesin is provided which has satisfactory mechanical strength and, at the same time, has, imparted thereto, for example, ion-exchange capacity, hydrophilicity, adhesive property, or abrasion resistance.
