Quantitative 13C NMR Analysis of Isotactic Ethylene–Propylene Copolymers Prepared with Metallocene Catalyst: Effect of Ethylene on Polymerization Mechanisms

Low molecular weight homopolypropylene and ethylene–propylene copolymers with low ethylene content have been produced with a highly stereoselective metallocene catalyst in the presence of dihydrogen. Quantitative 13C NMR analysis allowed the detection of regioirregular (2,1-insertions) propylene uni...
