| Abstract: | New results are reported on the superheating behaviour of ultra high modulus polyethylenes which have been restrained from shrinkage during the melting programme. Very high dagrees of superheating were observed, which were somewhat dependent on the polymer molecular weight. It is considered that the ultra high modulus polyethylenes do not contain extended chain crystalline material, and that the superheating effects are associated with the presence of a molecular network which can be prevented from relaxing by mechanical restraint. |
