Method of preparing rosin esters of improved thermal stability |
| abstract |
Alkali metal and alkaline earth metal salts of hypophosphorous and phosphorous acid are used to catalyze the esterification of rosin with a polyol. The method is an improvement in that reaction time is shortened and the ester product exhibits improved color and thermal stability. |
