52. In this comparison, we refer to literature data on other UHMWPE fiber samples; this is permissible because the chain flip rate is relatively insensitive to the crystallite thickness (Mansfield, M.; Boyd, R. H. J. Polym. Sci., Polym. Phys. Ed. 1978, 16, 1227-1252) in the 100 nm range that is relevant for UHMWPE fibers (Hu, W.-G.; Schmidt-Rohr, K., submitted to Polymer).
