Chemical Shift Parameters of the Substituent of 15 Ethylene Vinyl Compound Copolymers

The substituent chemical shift(SCS) theory is used to treat the 13C NMR spectra of 15 ethylene vinyl compound copolymers(EV). They are: (1) ethylene olefine copolymer including (a) ethylene-propylene copolymer (b) ethylene-1-butene copolymer (c) ethylene-4-methyl-1-pentene coplymer (d) ethylene-1-hexene copolymer (e) ethylene-1-octene copolymer; (2) ethylene vinyl oxygen compound copolymer including (a) ethylene-N, N-dimethyl aminoethyl methacrylate copolymer (b) ethylene-acrylic acid copolymer (c) ethy-lene-acrylic acid copolymer (d) ethylene-vinyl acetate copolymer (e) ethylene-vinyl alcohol copolymer (f) ethylene-carbon monoxide coplymer; (3) ethylene-halogenide copolymer and others including (a) ethylene-vinyl chloride copolymer (and/or chlorinated polyethylene) (b) ethylene-vinyl bromide copolymer (c) ethylene-vinyl cyanide copolymer (d) ethylene-styrene copolymer (and/or hydrogenated buatdiene-styrene copolymer). Finally the SCS parameters of 15 substituents are obtained.
