Measurements of photoemission of various high polymers were carried out in the wavelength region between 160 and 780 nm. The number of photoelectrons is changeable during the measurement depending on the wavelength of incident light because of surface charge-up, photoexcitation of electrons and other effects. The threshold energy of photoemission depends on the light intensity used for illuminating the sample. It is found that high-intensity illumination is necessary to obtain precise threshold energy values for high-polymer samples. For all polymer samples examined, the threshold energies of photoemission were from 3 to 3.5 eV, which are considerably smaller than the values corresponding to the depths of HOMO levels.
