Elastic hardened epoxy resin polymers prepared by the reaction of a liquid polyepoxy resin with the amino-terminated hydrolysis products of enamine- or ketimine-terminated adducts formed by reacting a polyalkylene ether glycol with a polyisocyanate to form a polyether urethane and then reacting the polyether urethane with an enamine or ketimine having an hydroxy group. |
