Abstract

Esterified epoxy resins are prepared in two stages: (i) by reacting (a) one or more monocarboxylic aliphatic acids, (b) a polyglycidyl ether of a polyhydric phenol, the ether having a 1,2-epoxy equivalency greater than 1, and (c) a dihydric phenol at elevated temperatures to obtain a polyhydric alcohol free of terminal 1, 2-epoxy groups, and (ii) reacting the polyhydric alcohol with one or more monocarboxylic aliphatic acids at elevated temperatures. In stage (i) compounds specified are (a) linseed, soyabean, castor and dehydrated castor oil acids, (b) bis-phenol A-epichlorohydrin epoxy resins and (c) bisphenol A, hydroquinone and resorcinol. There may be added in stage (i), Ca, Li or Na naphthenates or octoates as catalysts, xylene as a solvent and phosphoric acid as a colour improver. In stage (ii) the polyhydric alcohol may be partially or completely esterified: acids specified are linseed, soyabean and dehydrated castor oil acids. The final esters are soluble in xylene and mineral spirits: if the esters are derived from drying oil acids, driers e.g. Co naphthate may be added, and if not, the esters may be used as plasticizers for urea- and melamine-formaldehyde resins.ALSO:The invention comprises polymeric polyhydric alcohols free of terminal 1,2-epoxy groups and having the general formula: <FORM:0873252/IV (b)/1> where R is a monocarboxylic aliphatic acid residue, R1 and R2 are alkyl radicals of 1-4 C and y is 4 to 51. They are prepared by reacting (a) one or more monocarboxylic aliphatic acids, (b) a polyglycidyl ether of a polyhydric phenol, the ether having a 1,2-epoxy equivalency greater than 1, and (c) a d?hydric phenol at elevated temperatures. In the examples there are reacted in the presence of xylene and Ca naphthenate, (a) linseed oil, dehydrated castor oil or soya bean acids, (b) bis-phenol A/epichlorohydrin epoxy resins and (c) 2,2-di(4-hydroxyphenyl) propane to provide esters of the above formula where y is 7, 15, 19 or 32. These diesters are then reacted with further quantities of the acids to partially or completely esterify the remaining hydroxyl groups. It is stated in the Specification that Li or Na naphthenate or Ca, Li or Na oleate may be used instead of Ca naphthenate, and that castor oil acids may be used.
