✦ Synopsis

The ESR method has been used to investigate the structure and properties of highly drawn ultra-high molecular weight polyethylene fibres. The values of Tsoo, rotational correlation times and the free radical decay curves for fibres of various draw ratios have been obtained from ESR spectra. The model of soft domain formation in fibres at high draw ratios is used to explain the experimental results. K e y words: ultra-high molecular weight polyethylene fibres, spin probe method, correlation time, molecular mobility, ESR spectra.

For ESR studies of molecular rotation in liquids, it is desirable to match the spin probe as closely as possible to the solvent molecules. In this work the solvents were model lubricants whose overall motion has been characterized from carbon-13 NMR relaxation measurements. Two compounds were studie
