Helical conformation hypothesis

Iir.2.2. Another hypothesis is that the transition is due to a helix-coil-like transidem. This hypothesis has been proposed by Boyer for the transition in poly(4-mediyl pentene-1) (P4MF1) which crystallizes in a helical conformation. Closely related is the idea of die saturation of a chain molecule with defect-like kinks reuining the local chain axis. would then mark die stability limit of these chain stiuctures. In n-alkanes this special process of defect incorporation already starts in the solid phase. ... [Pg.297]
