Abstract

The effects of various gases on irradiated acrylamide and methacrylamide were studied by ESR. The results are not the same with irradiated monomers and irradiated polymers. Nitrogen oxide and hydrogen sulfide are known as radical scavenger, but they act as radical transformers for these samples. In source and postirradiation reaction of polyacrylamide or polymethacrylamide with hydrogen sulfide give rise to broad spectra having a g factor of 2.0267 and the new radicals produced here are concluded to be of the RS^.^ type.

## Abstract Electron spin resonance spectra of the irradiated monomers and polymers of both acrylamide and methacrylamide were studied. On thermal treatment, the spectra are changed both in their patterns and in intensity. The polymerization yield of these monomers after irradiation followed by the
