The ester comprises the reaction product of (a) a polyhydric alcohol component comprising at least 50 mole % of penterythritol, and (b) a carboxylic acid component comprising: (i) at least one linear or branched monocarboxylic acid having 2 to 7 carbon atoms; (ii) at least one branched monocarboxylic acid having 8 to 15 carbon atoms; and (iii) at least one polycarboxylic acid having 2 to 8 carbon atoms; wherein the ratio of the number of acid groups derived from the monocarboxylic acid(s) (i) to the number of acid groups derived from the monocarboxylic acid(s) (ii) is between about 0.9 and about 1.1 and the number of acid groups derived from the polycarboxylic acid(s) (iii) is between about 15% and about 25% of the total number of acid groups derived from the carboxylic acids (i), (ii) and (iii).Type: GrantFiled: September 16, 2010Date of Patent: August 27, 2013Assignee: Chemtura CorporationInventors: Dale Carr, Jeffrey Hutter, Edward T. Hessell, Richard Kelley, Roberto Urrego
