Abstract: Polyester resins are produced from unsaturated dicarboxylic anhydrides which are modified with a C.sub.10 hydrocarbon concentrate. They are superior to the known resins made by the hydrolysis method containing the hydrocarbon concentrate in that the dicarboxylic anhydrides used in the preparation of the resins are hydrolyzed with an amount of water always less than the amount of maleic anhydride and/or hydrocarbon on a molar basis. After the hydrocarbon addition reaction of the in situ generated acid, the reaction is heated to 140.degree. C. to 185.degree. C. in order to generate cyclopentadiene or similar C.sub.5 hydrocarbons and form endomethylene tetrahydrophthalic anhydride (carbic anhydride) or other similar Diels-Alder products from the remaining unreacted maleic anhydride and hydrocarbon, generally prior to the addition of other resin forming chemical intermediates e.g. polyols.
