Abstract

A pulsed nmr analysis system (figure 1a) for polymer mate-rials (S2) extracted from industrial processes at a mobility enhanc-ing temperature (figure 3) (at or above glass transition temperature for amorphous polymers, at the crystalline transition temperature for crystalline and semi-crystalline polymers). The sample is measured via nmr techniques and results correlated to viscosity and melt in-dex or melt flow (which are related to average molecular weights).
Substantial improvement of correlation of nmr derived constants and equations of a free induction decay curve with the foregoing polymer properties is obtained via (1) conducting the nmr process at a mobility enhancing temperature (normally elevated compared to the industrial process temperature of the industrial process) and (2) holding temper-ature substantially constant at such elevated temperature.
