摘要：
The 188.6 MHz 13C NMR spectra of a homologous series of copolymers were obtained from polymerization of ethylene/1-hexene, ethylene/1-octene, ethylene/1-decene, and ethylene/1-dodecene. The resulting spectra permit the resolution of unique 13C resonances from polyethylene chain branches at least up to 10 carbons long. Data from this study confirm the potential for using ultrahigh field NMR to study structure-property relationships for this most important commercial polymer.
