From potassium alkalide and benzyl glycidyl ether to crown-like macroinitiator with alkoxide active centres

Cyclic oligoether with alkoxide groups is obtained in the reaction of alkalide K−, K+(15-crown-5)2 with benzyl glycidyl ether. This oligoether contains potassium glycidoxide units and benzyl glycidyl ether units. Its use as a macroinitiator should lead to star-shaped polymers with a cyclic core.
