|Summary||Experimental data are presented on the variation of the plateau modulus for ultra-high molecular weight polyethylene (UHMWPE) as a function of solvent loading when the polymer is in the swollen state. The data show that the modulus follows the same form as that of a swollen crosslinked rubber. Using the plateau modulus as a measure of entanglement density we are able to correlate the subsequent solid state hot drawing of the preswollen UHMWPE with entanglement levels in the swollen material. A comparison between gel spinning and swell drawing data is made. © 1991.|
