Differential spectra have been obtained of a number of irradiated polyamides and monomeric amides. These spectra indicate that both free radical and molecular products are produced as primary products. The transient colored products (which are believed to be free radicals) and molecular products appear to be in the amine portion of the molecvle for the most part. The approximate G yield for radical production in nylon 66 is 5.8, and the approximate molar extinction coefficient of the free radical at 355 mμ is 690.
