Poly(ethylene terephthalate) (PET) films were grafted with n-vinyl-2-pyrrolidone ( n-VP) using an azobisisobutyronitrile (AIBN) initiator. Films were pretreated in dimethyl sulfoxide (DMSO) for 1 h at 140ЊC before the polymerization reaction was carried out. Variations of graft yield with time, temp
