Abstract
This invention relates to phenolic-modified rosin terpene resins prepared by the reaction of a rosin, a terpene and a phenol, wherein the weight ratio of rosin to phenol is from about 2.00 to about 3.00 and wherein the weight ratio of rosin to terpene is from about 1.40 to about 2.40. The phenolic-modified rosin terpene resins of this invention can be used as tackifers to form hot melt adhesives that can be applied at low application temperatures and more preferably hot melt adhesives also having high heat resistance and good cold adhesion.
