Abstract: Compounds containing peroxy linkages connecting similar polyol ester constituents are described. These peroxy di-ester polyols are prepared by the direct esterification of peroxy diacids with polyols, in the presence of a strong mineral acid catalyst. The peroxy di-ester polyol products function as free radical initiators and grafting bases in the graft copolymerization of unsaturated monomers with polyols. These graft copolymers are useful in the formulation of polyurethanes.

Abstract: Novel polyfunctional compounds and a novel process for their preparation are disclosed. These compounds may be converted into the acid or salt forms of cis and trans aconitic acids as well as into a racemic mixture of isocitric acid, alloisocitric acid and the lactones of isocitric acid and alloisocitric acid and their salts. All of the acid and salt forms produced are useful as metal sequestrants and/or detergent builders. The novel polyfunctional compounds can also be saponified to their corresponding alkali metal salts which, in turn, are also metal ion sequestering agents and detergent builders. The polyfunctional compounds are the reaction products obtained from the reaction of selected salts of monoalkyl esters of maleic acid with selected active hydrogen containing compounds.
