M. Bednarek et al., Branched polyether with multiple primary hydroxyl groups: polymerization of 3-ethyl-3-hydroxymethyloxetane, MACRO RAPID, 20(7), 1999, pp. 369-372
Cationic polymerization of 3-ethyl-3-hydroxymethyloxetane gives branched, s
oluble macromolecules with multiple glycolic end groups. There are approxim
ately 3-4 "normal" units per one branched unit.
