Abstract

Rosin is one of natural recycled resource which is rich in our country . Its mainly elements is tricyclic diterpenoid resin acid , rosin and disporportionated﹑hydrogenated rosin via esterification to overcome rosin itself existed many shortages,such as easy to suffer from oxidation,colour and luster unsteadiness,brittle,low softening point and expand rosin in many industry application scope . The research on rosin catalysis,esterification turning nature and the application of esterified products in the preparations of hot melt adhesives were reviewed in this paper based on the analyzing the studies in the field during the last decade, and has a prospect to the study .
