Polyether hybrid epoxy curatives

摘要

This invention relates to a polyether-amido-amine compound, obtainable by a two-step reaction of a poly-etheramine with an alkyl acrylate and a polyalkyle-neimine, whereas the polyetheramine and the polyalkyleneimine have at least one primary or secondary amine group, in which the first step comprises the reaction of the polyetheramine with the alkyl acrylate and the second step comprises the reaction of the polyalkyleneimine with the product of the first step. The invention also relates to a method for synthesizing a polyether-amido-amine compound by a two-step-reaction. Another object of this invention is a curable composition containing at least one polyether-amido-amine-compound of this invention and a method for coating the surface of a substrate or for binding at least two substrates together using such a curable composition.
