LIGHT-COLORED ROSIN ESTERS AND ADHESIVE COMPOSITIONS

摘要

Rosin esters that are both light-colored and color stable may be produced by reacting rosin with an organic compound containing two or more hydroxyl groups each separated from each other by at least four carbon atoms. With appropriate choices for the esterification catalyst and antioxidant(s), the rosin ester may be useful as a tackifier, and can be formulated into an adhesive composition. The adhesive compositions will further comprise an appropriate adhesive polymer.
