54. Spin-lattice relaxation rates suggest that the rate of polymer chain relaxation inn interfacial regions is between those in crystalline and amorphous regions. Spin-lattice relaxation in the crystalline part of linear polyethylene is slower than that in the amorphous part by 2 orders of magnitude. Hentschel, D.; Sillescu, H.; Spiess, H. W.
