Resonances in the 75.5 MHz 13C-NMR spectrum of poly(styrene oxide) (PSO) and of block and statistical copolymers of styrene oxide (SO) and ethylene oxide (EO) have been assigned with the aid of DEFT subspectral editing. Both primary and secondary hydroxyl end-groups have been identified in PSO. A si
