Research Center, Hercules Incorporated, 19894, Wilmington, DE, USA aut Analysis of NMR triad distribution in ethylene/1-butene copolymers [Elektronische Daten] [H. Cheng] Summary: For Ziegler-Natta polymers where the catalyst system can contain more than one active site, the analysis of NMR triad distribution data needs to be carried out with care. The best result is obtained when the NMR data of fractionated polymers are available. An analysis of the triad sequence distribution from the ethylene/1-butene copolymers indicate that the data are compatible with the occurrence of three discrete catalytic sites.
