Rosin has been found to react extremely rapidly with commercially available olefin 1,2‐epoxides to give hydroxy monoesters. These monoesters have been reacted further with rosin to give diesters. The diesters are ester gums, which are modified by the presence of a long aliphatic chain in the molecule. Preliminary results indicate that they are useful as tackifiers for SBR rubber.
