1. A method to produce an alkyd polymer composition, wherein the method comprises the steps of:
a) alcoholysis of an alcoholysis mixture, wherein the alcoholysis mixture comprises:
i. between 20 and 90 weight percent based on the weight of the alcoholysis mixture of at least one fatty acid ester,
ii. between 5 and 80 weight percent based on the weight of the alcoholysis mixture of at least one sugar alcohol having at least 6 carbon atoms, wherein the at least one sugar alcohol is capable of forming one or two cyclic ether rings through intramolecular cyclization,
iii. no poly acid nor an anhydride compound;
wherein the alcoholysis is performed at an alcoholysis temperature and wherein the alcoholysis produces, at the end of an alcoholysis time, a cyclic ether- and hydroxyl-containing composition which exhibits a plurality of peaks in the range of 75-90 ppm on a spectra obtained from C13 Nuclear Magnetic Resonance (NMR) spectroscopy and wherein the alcoholysis produces at the end of the alcoholysis time at least 0.001 mole of cyclic ether derived from the sugar alcohol per gram of cyclic ether- and hydroxyl-containing composition as determined by grams of produced water, wherein the grams of produced water and the moles of cyclic ether derived from the sugar alcohol per gram of cyclic ether- and hydroxyl-containing composition are related by the formula:

b) condensation of the cyclic ether- and hydroxyl-containing composition produced by the alcoholysis step a) with between 5 and 200 weight percent, based on the weight of the cyclic ether- and hydroxyl-containing composition of at least one of a poly acid or an anhydride compound,
wherein the condensation step b) takes place after the alcoholysis step a), wherein the condensation step b) takes place at a condensation temperature, and wherein the condensation step b) forms the alkyd polymer composition.
