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.
具有以下公式的化合物:其中Y为--XCH.sub.2 CH.sub.2 --X--,--X(CH.sub.2 CH.sub.2 X).sub.2或##EQU2##,p为1至4,每个X为O或NH,N-烷酰基,N-苯甲酰基,其中苯环可以选择性地取代为--NO.sub.2,--NH.sub.2或--CH.sub.3,N-烷基或N-.beta.-羟基烷基,每个碳原子数最多为8,其中N的总数为1至3。这些化合物可以通过在亲电试剂存在下打开氧环丙烷环而聚合,或者氧环丙烷环可以水解为二羟基基团并与二酸卤化物反应形成聚酯或与二异氰酸酯反应形成聚氨酯。这些单体和聚合物都可以与金属离子形成络合物,并可用于从溶液中分离这些离子。
