  • Oligoesters and compositions thereof
    Patent number: 10435586
    Abstract: An oligoester composition is disclosed, which is a reaction product of a reactant mixture comprising one or more rosins selected from the group consisting of tall oil rosin and gum rosin; at least 15% by weight of one or more monocarboxylic acids comprising 6-36 carbon atoms; and one or more polyhydric alcohols comprising 2-36 carbon atoms, wherein each hydroxyl group of the polyhydric alcohol is separated from the other hydroxyl groups by at least 2 carbon atoms. A method for preparing an oligoester composition is also provided. Also disclosed is an oligoester composition which is an esterification reaction product of one or more rosins, one or more monocarboxylic acids, one or more polyhydric alcohols, and optionally one or more polycarboxylic acids. The composition has a weight average molecular weight of from 500 g/mol to 8,000 g/mol and a Tg of between ?80° C. and 100° C.
