Polymerization of glycidol and its derivatives: A new ...

Anionic (KOH) polymerization of glycidol, or its trimethylsilyl ether (TMSGE) followed by hydrolysis, gives a low molecular weight, largely amorphous polymer that is not the reported 1,3‐polyglycidol but, based on 13 C‐NMR, largely a 1,4‐poly(3‐hydroxyoxetane) with much branching. This result is achieved by a simple rearrangement of the usual, propagating secondary oxyanion to a ...
