Gamma‐radiation‐induced graft copolymerization of N ‐[4‐( N ′‐substituted amino carbonyl)phenyl] maleimide onto poly(vinlyl chloride) films

Three types of N [4‐( N ‐substituted amino carbonyl)phenyl] maleimide (RPhMI: N ‐substituent (R) = phenyl, cyclohexyl, p ‐chlorophenyl) were grafted onto poly(vinyl chloride) (PVC) films by using gamma irradiation. The effects of different parameters on the graft yield were investigated. These parameters included radiation dose and monomer concentration. Thermal properties of the grafted polymer were investigated by the determination of dehydrochlorination rate, thermal gravimetric behavior, and UV stability.
