An alkyd polymer composition for fast-drying, low VOC applications is provided. The alkyd polymer incorporates a minimum required level of a cyclic ether- and hydroxyl-containing composition formed from a sugar alcohol during the alcoholysis step while synthesizing the alkyd polymer. The disclosure also relates to the cyclic ether- and hydroxyl-containing composition which must have a minimum required level of cyclic ether structure incorporated therein in order to produce a sufficiently fast-drying alkyd polymer. Methods of making the cyclic ether- and hydroxyl-containing composition and the alkyd polymer comprising, as polymerized units, the cyclic ether- and hydroxyl-containing composition and a poly acid and/or an anhydride compound, as well as an optional polyol, other than the sugar alcohol, are also provided. Also provided is a 13 C NMR method of characterizing the necessary minimum required level of cyclic ether ring structure in the cyclic ether- and hydroxyl-containing composition and the alkyd polymer formed therefrom.
