Gum Rosin Derivatives
Gum Rosin Ester are based on gum rosin and are comprised of several kinds of modified rosins, ester gums, rosin-based phenolic resins and other rosin resins.
There are four process methods of esterification, disproportionation, hydrogenation, polymerization and other reactivities.
