<p>Novel polyetheramine compounds, useful as curing agents in epoxy adhesive compositions, having the structure: <CHEM> where x is 1 to 4, y is 0 to 3 and R is the organic residue of a polyol having one of the formulas: <CHEM> where m is 2 to 12 and n represents a number of repeating units so as to provide a polyol having a number average molecular weight of about 400 to 12,000, or <CHEM> where Y is a divalent, trivalent or tetravalent organic radical with a valence (functionality) equal to a, a is 2 to 4, m is 2 to 12 and n represents a number of repeating units so as to provide a polyol having a number average molecular weight of about 400 to 12,000. In another embodiment, the polyetheramine compound is used as a curing agent for a polyepoxide compound to provide an epoxy adhesive composition having improved toughness properties.</p> |
