Abstract
A novel process for producing novel curable, liquid, hydroxyl-terminated epoxy polyether polymers by the direct polymerization of vinyl epoxy ether monomers in the presence of a strong alkali, to form a hydroxyl-terminated vinyl polyether polymer, followed by the epoxidation of the vinyl groups to form a novel curable, liquid hydroxyl-terminated epoxy polyether polymer which is stable against unintended polymerization in view of the epoxidation of the vinyl groups and is rapidly curable with the addition of conventional multifunctional curing agents.
