ABSTRACT:
A process and an apparatus for carrying out the process which causes acceleration of photodegradation of polymer substances. The process comprises irradiating a polymer substance with a low wavelength light and then a high wavelength light in an atmosphere with a specified humidity. The apparatus contains an irradiation lamp for irradiating a polymer substance, a rotating mounting plate for supporting the polymer substance, and humidifying means for creating a predetermined humidity for the photodegradation of the polymer substance. The photodegradation process and apparatus are used to precisely determine the useful life of polymer substances.
