Description
Summary:In order to improve the radiation stability of aliphatic polymers, radiation-induced graft polymerization of styrene onto low-density polyethylene (LDPE) has been studied. Two methods, namely, simultaneous irradiation and pre-irradiation method, were treated. In the case of simultaneous irradiation, it was indicated from the dependency of percent graft on monomer concentration and absorbed close that grafting efficiency was reduced by the increase in the homopolymerization of styrene. On the other hand, more highly grafting polymer could be prepared by the pre-irradiation method. Depth-profile of grafted phenyl ring was also analyzed by means of micro-FT-IR spectroscopy. Recently, radiation stability of the obtained graft polymer was tested.
