Abstract: A process for the manufacture of glycidylesters of branched monocarboxylic acids, comprising (a) the reaction of the &agr;-branched monocarboxylic acid with a halo substituted monoepoxide such as an epihalohydrin (e.g. epichlorohydrin), in a 2-20 molar excess, in the presence of water and a water-miscible solvent as solvent, and in the presence of a catalyst, in an amount of at most 45 mol % of the molar amount of the monocarboxylic acid groups, and preferably at most 30 mol % at a temperature in the range of from 50 to 110, during a period in the range of from 0.8 to 2.5 hr, (b) addition of additional alkali metal hydroxide or alkali metal alkanolate up to about an equimolar amount as to the monocarboxylic acid and reaction at a temperature of from 40 to 80° C.

Abstract: Linear, tertiary carboxyl functional polyester resins suitable for the production of coatings having excellent outdoor durable properties, the polyester resins obtainable by reaction ofa) at least one aromatic and/or cycloaliphatic carboxylic acid compound A comprising two aromatic- and/or secondary aliphatic carboxyl groups or the anhydride thereof,b) at least one hydroxyl compound B comprising two aliphatic hydroxyl groups, which groups each independently may be primary or secondary hydroxyl groups,c) at least one hydroxyl substituted carboxylic acid compound C comprising at least one tertiary aliphatic carboxyl group and two aliphatic hydroxyl groups, which groups each independently may be primary or secondary hydroxyl groups, andd) optionally one carboxylic acid compound D comprising one carboxyl group, the molar ratio of compounds A:B:C:D being (X+Y-1):X:Y:Z,wherein X ranges from 2 to 8, Y ranges from 2 to 8, and Z ranges from 0 to 2.
