Copolymerization of propene oxide with carbon with carbon dioxide: aselective incorporation of propene oxide into the polycarbonate chains, determined by 100 MHz 13C n.m.r. spectroscopy
Abstract
13 C N.m.r. spectroscopy has established that propene oxide–carbon dioxide copolymers prepared with diethylzinc-based catalysts can contain significant amounts of inverted propene oxide units, in contrast to the exclusively head-to-tail structured previously.
