Compound having the formula ##EQU1## WHEREIN Y is --XCH.sub.2 CH.sub.2 --X--, --X(CH.sub.2 CH.sub.2 X).sub.2 or ##EQU2## p is 1 to 4, and each X is O or NH, N-alkanoyl, N-benzoyl wherein the benzene ring is optionally substituted with --NO.sub.2, --NH.sub.2, or --CH.sub.3, N-alkyl or N-.beta.-hydroxyalkyl each of up to 8 carbons and wherein the total number of N is 1 to 3 are disclosed. The compounds can be polymerized by opening of the oxetane ring in the presence of electrophilic agents, or the oxetane ring can be hydrolyzed to a dihydroxy group and reacted with diacid halides to form polyesters or with diisocyanates to form polyurethanes. Both monomers and polymers complex metal ions and can be used to separate such ions from solutions.
