Abstract

A polyol having a substituent of formula (I) attached via a carbon-carbon single bond to a saturated carbon atom in a fatty acid hydrocarbyl group; wherein R 1 and R 2 are esterified residues of aliphatic or cycloaliphatic diols; and from 0 to 15 wt % of esterified residues of at least one C 4 -C 12 anhydride, C 4 -C 12 diacid or C 4 -C 12 lactone, not including units of formula (I) attached to a fatty acid hydrocarbyl group.

Description

technical field [0001] The present invention generally relates to polyols produced from biological materials. Background technique [0002] The use of triglycerides in the preparation of alkyd resins is well known. Typically, these resins are prepared without modification of the fatty acid chains, but by reacting triglyceride ester groups with acids and diols to form polyesters. Such resins are typically of high molecular weight and require solvents to deliver the resin in coating applications. [0003] The preparation of polycondensation products usable in paints has been described by reacting triglycerides with maleic anhydride followed by ethylene glycol. For example, US Patent 2,188,882 to Clocker discloses the reaction of linseed oil with 10% by weight maleic anhydride at 250°C, and then reacting the resulting product with a small amount of ethylene glycol at about 180°C. However, the material produced this way is extremely viscous and must be dispersed in a solvent ...
