Studies on Effects of Radiation-Induced Crosslinks in Polyethylene in Molten State by High-Resolution Solution13C NMR (Ⅱ)

Abstract

Abstract: Crosslinking structure formed during irradiation of polyethylene with the doses just lower than the gel dose,and the effects for this formation were investigated by ¹³C NMR Spectra. It is shown that formation of both "H" and "Y" type not only have a connection with irradiated doses, but also a few of other structures containing in the original PE. Nevertheless, are not related to the molecular weight for the PEsamples. The reaction mechanism and the principal factors influencing radiation-induced links arc also discussed for PEin the molten state.

Key words: Polyethylene, ¹³C NMR of Polymer, Radiation-induced crosslink
