CARBON-13 ASSIGNMENTS OF EPDM/PP ATACTIC BLENDS BY DEPT AND HETCOR

摘要

The structure of the elastomeric ethylene-propylene-diene terpolymer/atactic polypropylene (EPDM/PPA) blends were assigned by NMR using DEFT (distortionless enhancement by polarization transfer) and HETCOR (heteronuclear correlation) sequences. These methods were carried out to elucidate solid-state C-13-NMR assignments of polymeric blends. (C) 1996 John Wiley & Sons, Inc. [References: 8]
