The temperature required for this process is determined by extrapolating lamellae to be infinitely thick on a Hofmann-Weeks plot. SAXS (“saxes”) spectra depicting this process becomes more uniform as its “surface” mechanism is supplanted by “sequential” and then “stack” mechanisms. This process causes ordered chains to disappear and reduces a polymer’s degree of crystallinity to zero. This process occurs at the endothermic extremum of Q, the peak on the right-hand side of a DSC trace. (-5[1])In a test for (-5[1])(*) polydispersity, the range for this process (-5[1])is measured by staring at a sample through a capillary window (10[2])while slowly jacking (10[1])up the temperature. (10[1])Past the glass transition, thermoplastic (10[1])polymers can flow even without undergoing this process. For 10 points, (10[1])name this phase transition (10[1])that occurs when solid polymers (10[1])liquefy. ■END■ (10[3])
