We also investigated the suitability of other epoxides than PO to our new methodology (ESI Section S6) and found a range of monosubstituted and alicyclic epoxides (Figure ) to likewise undergo ROTERP with S8 and CS2 (Table ). Moving to monosubstituted epoxides with longer alkyl chains, such as butylene oxide (BO) and 1,2decylene oxide (DO), gave similar results as the ROTERP of PO under the same conditions, producing a poly(OSO-alt-Sx) with head-to-head-alttail-to-tail regioselectivity. The ROTERP of cyclochexene oxide (CHO) yielded materials with an increased Tg of 70 ºC at a somewhat reduced linkage selectivity compared to the monosubstituted epoxides. This is in line with findings by Werner and Komber et al. who observed reduced linkage selectivity in the parent CS2/CHO ROCOP. Glycidyl ethers can also be terpolymerised with almost quantitative linkage selectivity and excellent OSO-alt-Sx (head-to-head-alt-tail-to-tail) selectivity, yielding materials with a Tg below room temperature (-12 ºC) for the ethyl derivative EGE and above room temperature (+30 ºC) for the phenyl derivative PGE. Lastly, terpolymerisation of styrene oxide (SO), which is an intrinsically challenging epoxide in ROCOP catalysis, could also be achieved although maximum conversion and molar mass were reduced (Table ).
