Factors affecting the photo-induced graft copolymerization of methyl methacrylate onto fibrous polymer

Authors


Abstract

The effects of sample swelling, photosensitizer, and solvent on the photo-induced graft copolymerization of methyl methacrylate onto fibrous polymers such as Vinylon, nylon 6, and polyester were examined. Each separate factor, sample swelling, or solvent, or their combination, increased activity of polymerization. Only some sensitizer were effective. Studying the ESR spectra of photo-irradiated polymers also showed that either the sample swelling, the photosensitizer, or the organic solvent is very effective for the formation of polymer radicals under irradiation.
