Appreciable quantities of 4βvinyl pyridine and acrylamide have been grafted to nylon 6.6 by decomposing in their presence the peroxides and hydroperoxides formed on irradiating the polymer in air with Ξ³βrays. The kinetics of the grafting process is interpreted in terms of a diffusion of the monomer into the nylon. The enhanced dyeing of the amine grafts and the lowering of the surface resistance of the graft by quaternization with dimethylsulfate are also reported.

Radiation-induced graft copolymerizalion of styrene on to nylon-6 was performed by various methods, viz. liquid phase mutual irradiation, vapour phase mutual irradiation, and grafting on peroxidized polymer. Liquid phase mutual irradiation grafting was carried out in air either in the presence or in
Grafting of acrylamide (AAm) onto poly(vinyl chloride) (PVC) Γlms using gamma radiation has been carried out. The e β ects of di β erent parameters on the graft yield have been investigated. These parameters include radiation dose, monomer concentration, solvent composition, types of inhibitors and ac
