Abstract

The molecular motion of polyethylene has been studied in decalin-d18 solution by 1H n.m.r. relaxation with the isotopic dilution technique which can separate the proton spin-lattice relaxation times into the intra- and intermolecular contributions, intra T1 and inter T1. The temperature dependences of intra and inter T1s show that the intra- and intermolecular motions are in the extreme narrow region. These results, also, were compared with the results of molten polyethylene reported in our previous work.
