Continuous changes in the inner order of the crystalline lamellae during isothermal crystallization of poly(is an element of-caprolactone)

Abstract

Simultaneous time-dependent small-angle and wide-angle X-ray scattering experiments (SWAXS) can be used to detect changes in the inner order of the lamellae growing during polymer crystallization. In SWAXS studies of crystallizing poly(c-caprolactone) a delay in the development of the Bragg peaks relative to the increase of the Porod coefficient was detected. As indicated by the WAXS patterns, the weakening of the Bragg peaks is caused by innercrystalline disorder, which decreases with time.
