Oxetanes containing hydroxyl groups can conveniently be prepared using commercially available trimethylolpropane or penthaerithritol. The corresponding monomers, such as 3‐ethyl‐3‐hydroxymethyloxetane (EOX) have been polymerized cationically and it has been shown, that resulting polymers are branched. These polymers are of particular interest, since in contrast to some other polyhydroxyethers (like polyglycidol) all of the hydroxyl groups are primary ones. Moreover, all of the ‐CH 2 OH groups are attached to the quaternary carbon atoms. These features are rather unique and may be advantageous from the point of view of possible applications.
