Esters of rosin and olefin epoxides

  • Published:
Journal of the American Oil Chemists’ Society

Abstract

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.
