RADIATION-GRAFTING OF 2-BROMOETHYLACRYLATE ONTO POLYETHYLENE FILM BY PREIRRADIATION METHOD

摘要

Radiation-induced graft polymerization of bromoethylacrylate onto a low-density polyethylene (LDPE) film by preirradiation method in the presence of air has been investigated. The appropriate reaction conditions for the graft polymerization were determined. It was observed that the grafting is governed by several factors, such as preirradiation dose and grafting temperature. The degree of grafting increased rapidly with the initial reaction time and then leveled off to the final value. The optimum temperature for grafting was determined to be 55℃.
