ABSTRACT:
Advanced resins and unadvanced epoxy resins are disclosed wherein the unadvanced compound and at least a portion of the advanced epoxy resin contains at least one --O--R.sup.1 --O-- or --(O--CH.sub.2 --CHR.sup.2).sub.n --O-- group as a bridge between two groups selected independently from the group consisting of (1) a saturated or unsaturated cycloaliphatic group, (2) an aromatic group, (3) a group represented by the formula ##STR1## or (4) a group represented by the formula ##STR2## Also disclosed are nucleophilic derivatives thereof, as well as curable compositions and coating compositions containing the advanced or unadvanced epoxy resins or nucleophilic modified advanced or unadvanced epoxy resins. These advanced resins and unadvanced epoxy resins provide coatings with good flexibility or formability as exhibited by good flexural or formable properties determined by reverse impact, T-bend and wedge-bend tests, chip resistance, and with good corrosion resistance and throwpower.
