Abstract
Aliphatically modified rosin resins are prepared by reacting rosin esters with aliphatic monomers. These aliphatically modified rosin resins are compatible with metallocene catalyzed polyolefins and other aliphatic base polymers and are used as tackifiers in combination with metallocene catalyzed polyolefins and other aliphatic base polymers to form adhesive compositions for hot melt and pressure sensitive applications.
