Abstract

Rotational-echo double-resonance ¹³C{²H} NMR has been used to characterize the chain packing in a ¹³C, ²H-labeled ethoxyphenyl-substituted bisphenol A polycarbonate. Approximately 36% of the repeat units are locally ordered, and between 85% and 95% of carbonate linkages are trans. The local order in interchain packing is correlated with the local order of intrachain conformations of the carbonate linkages.
