RADIATION-INDUCED GRAFT COPOLYMERIZATION TO CELLULOSE. I. GRAFT COPOLYMERIZATION OF METHYL METHACRYLATE TO CELLULOSE INDUCED BY $gamma$-IRRADIATION
Dry filter paper treated in a solution of methyl methacrylate in acetone was irradiated with Co/sup 60/ gamma rays in the air. The grafting of methyl methacrylate to dry cellulose was very small, but grafting of methyl methacrylate to cellulose was induced efficiently by irradiating the filter paper in a mixture of methyl methacrylate, acetone, and water. Water accelerated the grafting. Dry cuprammonium rayon, after immersion in a mixture of 5.6 cc of methyl methacrylate and 1.4 cc of water; or 1.05 cc of methyl acrylate, 2.1 cc of water, and 3.85 cc of acetone for 24 hr or longer, was irradiated in the presence or absence of air. The lower the dose rate, the greater the grafting of methyl methacrylate to rayon. The percentage of grafting in the mixture of methyl methacrylate and water increased with increasing temperature. There was an induction period in grafting in air but not in a vacuum. (OID)
