摘要
The C-13 NMR spectral assignments for ethylene/1-hexene copolymers are reexamined. Revised assignments are obtained for the 34-36 ppm region. A computational scheme is devised to extract information on composition and sequence distribution from the spectral intensities. A computerized analytical approach that fits the observed intensities to statistical models is also available.
