Abstract

We have studied the thermal degradation of polymer samples of low density polyethylene (LDPE) and crosslinked polyethylene (XLPE) by ¹H nuclear magnetic resonance. The spin-lattice relaxation in these systems was explained using the two-phase model for semicrystalline polymers. It was found that the microscopic environments of the ¹H nuclei due to thermal degradation were reflected in the spin-lattice relaxation times (T₁) and the line shapes. The degree of crystallinity was also determined.
