Abstract: PURPOSE:To form an excellent uranium adsorbent in an optional shape by treating a polymerizable monomer having a functional group that can be converted to an amidoxime group and a polymerizable monomer having a functional group that can be converted to a cation exchange group by a radiation grafting method. CONSTITUTION:Ionizing radiations are irradiated beforehand to a base material; thereafter, the base material is brought into contact with a polymerizable monomer which is a polymer contg. a nitrile group and can be converted to an amidoxime group by reaction with hydroxylamine (e.g., acrolonitrile) and a polymerizable monomer contg. a cation exchange group or a functional group that can be converted to a cation exchange group (e.g., acrylic acid) or while the base material is held in contact with the polymerizable monomers, the ionizing radiations are irradiated thereto to produce a graft polymer. The graft polymer is caused to react with hydroxylamine and if the polymerizable monomer is the monomer having the functional group that can be converted to a cation exchange group, said polymer is subjected to alkali reaction, whereby the uranium adsorbent contg. the amidoxime group and cation exchange group coexisting in the graft chain is produced.

In regard to the frequency-phase characteristic of the waveguide 1 itself, the phase difference |ϕ| lowers rather suddenly in a frequency range near the frequency fc as the frequency f increases in a superwide band frequency range set between the frequency fc and the frequency 2fc. The difference |ϕ|slowly lowers in the following frequency ranges. During this lowering period, the difference |ϕ| lowers less than 90 degrees and thereafter lowers continuously in the same way. As a result, the straight line-circular polarized wave conversion is carried out as desired.
