Applications of 1 H— 19 F— 13 C Triple-Resonance NMR Methods to the Characterization of Fluoropolymers (original) (raw)

ACS Symposium Series, 1995

Abstract

ABSTRACT In this paper we illustrate some applications of 1D- and 2D-1H/19F/13C triple resonance NMR techniques for characterizing fluoropolymers. These methods can be used to achieve spectral simplification, to disperse resonances permitting resolution of clearly spaced peaks due to nuclei in various stereo- and monomer sequences, and to establish one-bond and multiple-bond connectivities in order to identify structure fragments. Various permutations of INEPT, HMQC, and HMBC NMR experiments are used to obtain illustrative data from poly(1-chloro-1-fluoro-ethylene-co-isobutylene) (PCFE-IB).
