    Abstract: An alkyd polymer composition for use in low volatile organic compound (VOC) containing products that exhibits a Gardner-Holt viscosity with 30 weight % mineral spirits at 25° C. that is less than or equal to Z4, a thy-hard time of less than 10 hours when tested with metal driers according to ASTM D 1640-03, and a clear appearance. The alkyd polymer composition includes, as polymerized units an alkyd polymer of one or more fatty acids; a sugar alcohol having at least 6 carbon atoms; a polyol with four or more hydroxyl functional groups; and an aromatic polyacid with two carboxylic acid groups located in a meta-position relative to one another. The alkyd polymer composition includes at least one aliphatic oxide ring having one or more peaks located between 75 to 90 ppm as measured using C13 Nuclear Magnetic Resonance (NMR) spectroscopy.

    Abstract: 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.

    Abstract: Waterborne dispersions including crosslinkable multistage polymeric particles useful in coating compositions are provided. The multistage particles have a last-formed layer that includes a diketone functionality that is capable of crosslinking via a dihydrazide component also included in the dispersion. Another embodiment of the waterborne dispersion further includes crosslinkable latex particles having a diketone functionality that are capable of crosslinking with each other and/or the multistage particles via the dihydrazide component. An emulsion polymerization process for forming the multistage particles also is provided. Also provided are coating compositions that contain either embodiment of the waterborne dispersions.

    Abstract: A dispersion of an alkyd-containing polymer dispersed in water is used to form a waterborne coating composition; the alkyd-containing polymer being an acrylic-modified alkyd polymer, a silicone-acrylic-modified alkyd polymer, or a mixture thereof. The resulting waterborne coating composition includes about 2 to about 30% by weight of one or more thermal insulating fillers with the remainder being the alkyd-containing dispersion, such that the coating composition contains about 30 to about 80% by weight of the water and about 2 to about 50% by weight of the alkyd-containing polymer. The coating applied therefrom exhibits at least one of the following properties: a thermal conductivity that is less than 100 mW/mK; a weight retention of at least 70% after being heated up to 400 C as measured by thermogravimetric analysis (TGA) with a heating rate of 20 C/min.; or a weight loss of less than 50% up to a temperature of 470 C as measured by the TGA.
