Abstract
A polymerizable composition comprises divinylbenzene dioxide and a polycarboxylic acid compound in an amount having 0,3 to 1,25 carboxyl equivalents per epoxy equivalent; the composition may also contain a lesser amount of a polycarboxylic acid anhydride to the extent of 0,75 carboxyl equivalents per epoxy equivalent, the total number of carboxyl equivalents per epoxy equivalent being not greater than 1,25 The cured resins have the recurring units:- <FORM:0866410/IV (a)/1> where Y is a polycarboxylic acid residue. Any of the o, m, or p-isomers of divinylbenzene dioxide, or mixtures thereof, may be used. Suitable polycarboxylic acids include saturated and unsaturated di- and tri-carboxylic acids. These may be wholly or partly replaced by polycarboxy polyesters prepared from polyhydric alcohols and excess polycarboxylic acid. The polyhydric alcohols include glycols, oxyalkylene glycols, alkane diols, tri- and tetra-hydric and higher polyhydric alcohols, polyvinyl alcohol, and epoxide reaction products. Examples are given of polycarboxylic acid anhydrides which may be used; these may also be saturated or unsaturated and include acid dianhydrides. Acid catalysts may be added to the compositions, e.g. mineral acids, sulphonic acid and metal halide Lewis acids, and they may be in form of solutions in organic solvents. The uncured or partially cured compositions may be dissolved in solvents such as xylene, methyl isobutyl ketone, ethyl-, butyl- and amyl-acetate and toluene, and applied as a coating composition which is subsequently completely cured. The examples specify the following polycarboxylic compounds: adipic acid, an adduct of succinic anhydride (3 mols) with glycerol (1 mol), glutaric acid, an adduct of phthalic anhydride (2 mols) with ethylene glycol (1 mol), sebacic acid, a mixture of adipic acid and phthalic anhydride, a mixture of sebacic acid and maleic anhydride, a mixture of maleic acid and glutaric anhydride, a mixture of methyltetrahydrophthalic anhydride and an adduct of glycerol and succinic anhydride. Also given for comparison are benzoic, acetic and butyric acids.
