By cross-linking with DVS, the values for the tenacity at break and the initial modulus were increased with cross-linking time, while the elongation at break was improved only moderately. On the other hand, drastic improvements in elongation at break were observed after EGDE cross-linking, up to 645% of its original length, although the tenacity at break and the initial modulus showed only slight improvements. After cross-linking, only minor changes in the degree of crystallinity of the fibers were observed by wide-angle X-ray scattering measurements., Article, TEXTILE RESEARCH JOURNAL. 80(12):1131-1137 (2010)}, pages = {1131--1137}, title = {Preparation of Polyrotaxane Fibers.
