Gamma irradiation of poly(alkyl methacrylates)

Gamma irradiation of poly(alkyl methacrylates)

A series of poly(alkyl methacrylates) were prepared from monomer of high purity and subjected to gamma irradiation. Gelation in the n‐alkyl series was detected for poly (n‐heptyl methacrylate) at 15 Mreps; gel was detected at lower doses as the length of the alkyl group increased. No gelation was fo...

Zusammenfassung:A series of poly(alkyl methacrylates) were prepared from monomer of high purity and subjected to gamma irradiation. Gelation in the n‐alkyl series was detected for poly (n‐heptyl methacrylate) at 15 Mreps; gel was detected at lower doses as the length of the alkyl group increased. No gelation was found on irradiation of poly (sec‐alkyl methacrylates) to relatively high doses; poly(sec‐nonyl methacrylate) remained soluble after 40 Mreps of irradiation. Correlation with earlier work on irradiation of poly(alkyl acrylates) is discussed.
