NMR METHOD OF DETERMINING AND REGULATING THE COMPOSITION OF POLYMER MIXTURES IN POLYMERIZATION

摘要

Proton-nuclear magnetic resonance relaxation curve of polymer mixture comprising defined polymer components differing in mean molar mass is recorded. The measured curve is matched with relaxation curve of the individual polymer components, to calculate the proportion of the polymer components. Independent claims are also included for the following: (1) regulation of composition of polymer mixture; and (2) polymerization of olefin.
