(1-Adamantyl)methyl glycidyl ether (AdaGE) is introduced as a versatile monomer for oxyanionic polymerization, enabling controlled incorporation of adamantyl moieties in aliphatic polyethers. Via copolymerization with ethoxyethyl glycidyl ether (EEGE) and subsequent cleavage of the acetal protection groups of EEGE, hydrophilic linear polyglycerols with an adjustable amount of pendant adamantyl moieties are obtained. The adamantyl unit permits control over thermal properties and solubility profile of these polymers (LCST). Additionally, AdaGE is utilized as a termination agent in carbanionic polymerization, affording adamantyl-terminated polymers. Using these structures as macroinitiators for the polymerization of ethylene oxide affords amphiphilic, in-chain adamantyl-functionalized block copolymers.
（1-金刚烷基）甲基缩水甘油醚（AdaGE）被引入作为用于氧阴离子聚合的通用单体，能够在脂肪族聚醚中可控地引入金刚烷基部分。通过与乙氧基乙基缩水甘油醚（EEGE）共聚并随后裂解EEGE的缩醛保护基团，可得到具有可调节数量的侧链金刚烷基部分的亲水性线性聚甘油。金刚烷基单元可控制这些聚合物的热性能和溶解度曲线（低临界溶液温度）。此外，AdaGE被用作阴离子聚合中的终止剂，得到金刚烷基封端的聚合物。将这些结构用作环氧乙烷聚合的大分子引发剂可得到两亲性的、链内金刚烷基官能化的嵌段共聚物。
