英文摘要 | Three ethylene-vinyl alcohol copolymers were studied by means of the substituent chemical shift (SCS) method. The SCS parameters of hydroxy (-OH) in two different solvents were obtained: in deuterium oxide/phenol (20/80 W/W ) the parameters are S 1 = 42.77±0.08ppm, S 2 = 7.15±0.06 ppm, S 3 (s)= -4.08±0.02ppm, S 3 (t) =-3.09±0.20ppm,S 4 = 0.48±0.03ppm, S 5 = 0.26±0.05ppm. In o-dichloro-benzen-d 4 S 1 (s)=44.79±0.61ppm, S 2 =7.40±0.00ppm, S 3 (s)=-4.51±0.17ppm, S 3 (t)=-3.13 ±0.00 ppm, S 4 =0.63±0.04ppm, S 5 =0.36±0.00ppm.Simultaneously the 13 CNMR spectra of EVA copolymers were assigned by using the SCS parameters obtained. |
