ABSTRACT:
The specification describes a process for making highly functionalized rosin ester resins; i.e., partially esterified rosin based resins. The resins are produced by reacting fortified rosin with a polyol at superatmospheric pressure in a closed reaction vessel while retaining at least a portion of the water formed during the esterification step in the reaction vessel, thereby limiting the reaction to a desired degree of partial esterification so that a relatively high degree of residual acid functionality is achieved in the final ester product. The process enables large scale production of resins with precise control of the degree of functionality of the resins thus produced. The products are particularly useful as binders in ink formulations.
