An oligoester composition which is a reaction product comprising a mixture of reactants: one or more rosins; at least 15% by weight of one or more monocarboxylic acids; and one or more polyols. A method of preparing an oligoester composition comprising (a) esterifying a mixture comprising one or more rosins, one or more monocarboxylic acids, and optionally one or more polycarboxylic acids and one or more polyols, as appropriate An oligoester composition is formed. An oligoester composition which is an esterification reaction product of one or more rosins, one or more monocarboxylic acids, one or more polyols, and optionally one or more polycarboxylic acids, wherein the weight average of the composition The molecular weight is from 500 g/mol to 8,000 g/mol and the Tg is between -80 ° C and 100 ° C. |
