Abstract: Homopolymers and copolymers of glycidyl esters are made by reacting the acids to be esterified with the corresponding polymer of tert.-alkyl glycidyl ether under substantially anhydrous conditions and in the presence of a strong acid catalyst, preferably a sulfonic acid. The reaction proceeds satisfactorily at about 100.degree.14 150.degree. C with displacement of the tert.-alkyl group by the acyl group of the acid and evolution of tert.-olefin. By use of the appropriate proportion of reactant acid and/or appropriate reaction time, any desired proportion of the glycidyl groups can be esterified.

Abstract: Linear copolymers of glycidol, glycidyl esters of unsaturated fatty acids and, optionally, alkylene oxides, are made by the reaction of an unsaturated fatty acid with a polymer or copolymer of tert.-butyl glycidyl ether in the presence of an acid catalyst. The products are polymerizable and copolymerizable with vinyl monomers and are useful as curable resins.

Abstract: Antistatic compositions for topical application to substrates, which comprise(a) a polymer of less than about 20,000 molecular weight consisting essentially of, in polymerized form, about 10 to 99 mole % alkylene oxide, of 2 to 4 carbon atoms, about 1 to 90 mole % glycidol and about 0 to 15 mole % of the glycidyl ester of a fatty acid of about 2 to 20 carbon atoms and about 0 to 15 mole % of the glycidyl monoester of a polycarboxylic acid,(b) a curing agent capable of cross-linking the polymer by reaction with the primary hydroxyl groups of the glycidol units, such as melamine-formaldehyde condensates, dialdehydes, polycarboxylic acids and their anhydrides, epoxy resins (polyepoxides), polyisocyanates, and the like and(c) a catalyst for the curing reaction, such as zinc fluoroborate, a sulfonic acid, phosphoric acid, ammonium sulfate or the like.

Abstract: New polymers are copolymers of glycidol, glycidyl esters of fatty acids, and, optionally, alkylene oxides. They are conveniently made by the reaction of a fatty acid with a polymer or copolymer of tert.-butyl glycidyl ether in the presence of an acid catalyst. They are useful as coatings, lubricants, plasticizers, textile antistatic agents and surfactants.

Abstract: In a process for removing --R groups, where --R is tertiary butyl or tertiary amyl, from a polymer containing the monomeric unit represented by the formula ##STR1## by contacting the polymer with a sulfonic acid, the improvement of contacting under essentially anhydrous conditions.
