    摘要: A polyester resin is the reaction product of plurality of a first compound and a plurality of a carboxylic acid anhydride. The first compound has hydroxyl groups. The carboxylic acid anhydrides react with the hydroxyl groups of the first compounds to form a plurality of first intermediate compounds. These first intermediate compounds have at least one hydroxyl group and carboxylic acid groups. A temperature of the first intermediate compounds is increased until the hydroxyl group of one first intermediate compound condenses with one of the carboxylic acid groups of another first intermediate compound. This condensing, or condensation, forms the polyester resin having an ester linkage and carboxylic acid groups. A second compound having at least one epoxy group and a carbamate compound can be subsequently reacted with the polyester resin. A coating composition includes the polyester resin and a cross-linking agent reactive with the polyester resin.

    摘要: A polyester composition has a number average molecular weight M.sub.n of between about 500 and about 1000, a weight average molecular weight M.sub.w of between about 600 and about 2000, a polydispersity below about 2, preferably below about 1.8, hydroxyl functionality between 2 and 3, a hydroxyl value of between about 160 and about 260, and an acid number below about 10. Less than about 5% of the OH groups of the polyester are pendent, the rest being terminal. Between about 10 and about 50 wt % of the monomers used to form the polyester composition are anhydrides having the formula: ##STR1## where R.sup.1 is a non-aromatic, saturated or unsaturated hydrocarbon chain having between 6 and 30 carbon atoms, R.sup.2 is hydrogen or a non-aromatic saturated or unsaturated hydrocarbon having between 1 and 8 carbon atoms, and R.sup.1 and R.sup.2 have, in total, between 8 and 30 carbon atoms. The polyester in conjunction with a hydroxyl-reactive curative provides a coating composition.

    摘要: A polyester composition having an average molecular weight of greater than 500 comprising a most prevalent compound having a main polyester chain containing at least 17 and fewer than 52 carbon atoms and at least 6 and fewer than 18 oxygen atoms, at least 52 weight percent of the molecules of said composition having a molecular weight within 50% of the average molecular weight of the composition. The polyester composition desirably contains at least 1.6 equivalents of unreacted hydroxy groups or at least 1.6 equivalents of unreacted carboxy groups per mole. The composition contains at least four equivalents of ester links in the main chains of the molecules per mole.The composition of the present invention is obtained by the method of the invention wherein alternating series of reactions are each driven essentially to completion where the final molecule of each reaction provides the only available reaction site for the next alternate monomer reaction. The reactions used are the reaction of an anhydride with a hydroxyl to give an ester and a carboxyl group and the reaction of an oxirane group with a carboxyl to give an ester and a hydroxyl group. To start the alternating reaction sequence either a polyol (to react with anhydride) or a polycarboxylic acid (to react with an oxirane) is used.
