Polymer bound palladium (Pd)complex catalysts with grafting acrylonitrile on inorganic compound(MgO,Y-molecular sieve and SiOz) by pre-radiation method were studied. The palladium - grafting polymers have been investigated by X-ray photoelectron spectrscopy(XPS). It is indicated that peak width of C1s and O1s spectra of MgO-g-PAN - Pd (radiation - induced graft) is wider than that of MgO -PAN - Pd(chemical method) and peak numbers of former are one more than later.According to the report in reference, this peak is attributed togroup. Thus, the graft acrylonitrile on MgO may complete through oxygen atoms in MgO and β-carbon atoms in acrylonitrile. The polymer catalyst obtained by radiation grafting is a higher active hydrogenation catalyst for olefines and better antitoxic than that of one obtained by chemical method, and it has selectivity for hydrogenation catalyst.
