Abstract: The theory of chemical shift effect of substituent was applied to the assignment of the 13C NMR spectra of the ethylene/propylene and ethylene/octene-1 copolymers. Using the parameters derived above and the DEPT technique, we then entirely assigned the 13C NMR spectra of the ethylene/propylene/octene-1 terpolymers synthesized in the presence of the same heterogeneous supported Ziegler-Natta catalyst, TiCl4/MgCl2/i-Bu3Al. The present paper also covers the terpolymer composition and the monomer sequence distributions of a series of ethylene/propylene/octene-1 terpolymers.

Key words: Chemical shift effect, 13C NMR, Ethylene/propylene/octene-1 terpolymer
