摘要

AbstractAn attempt has been made to graft copolymerize 4‐vinyl pyridine onto isotactic polypropylene hydroperoxide by mutual irradiation method in an aqueous medium. Polypropylene hydroperoxide has been prepared by irradiating recrystallized polypropylene beads from a Co60source in the presence of air. The resulting polypropylene hydroperoxide beads have been used as the backbone polymer and grafting of 4‐vinyl pyridine has been studied as a function of various reaction parameters. Optimum conditions for maximum percentage of grafting have been evaluated. Rate of grafting (Rg) has been determined as a function of preirradiation dose and initial monomer concentration. Water has been found to affect percentage of grafting. The graft copolymers have been characterized by spectroscopic method and isolation of the grafted poly(4‐VP) from the graft copolymer. A plausible mechanism is proposed to explain the mutual grafting of 4‐vinyl pyridine onto polypropylene hydroperoxide. © 1993 John WileyS
