Nuclear magnetic resonance (NMR) study of polyethylene terephthalate crystallization

Abstract

There are several reports of crystallization studies [1-3] by classical methods, e.g. dilatometry etc. Here we describe a standing the crystallization of polyethylene terephthalate (PETP) by means of the NMR impulse method and show that it can give informational additional to the usual kinetic characteristics, i.e. about changes in molecular movement during crystallization. © 1973.
