Presently described are bio-based hot-melt adhesive compositions including rosin acids or derivatives thereof and an amphiphilic agent that provide adhesives with a high softening point, improved heat resistance, low melt viscosity, and compatibility with hydrocarbon compositions including polyolefins and waxes used in hot-melt adhesives.

Amphiphilic additives as compatibilizers for rosin tackifiers in polyolefin hot-melt adhesives

The present description provides esterified fatty acid and/or tall oil compositions and their use as alternative plasticizers in adhesives formulations. These esters demonstrate similar or improved performance over adhesives industry standard plasticizers. The description also provides methods of manufacturing and using the same, for example, to improve or modify the performance of adhesive materials, such as, hot melt pressure sensitive adhesives and hygienic adhesives.

Fatty acid and rosin acid ester compositions for use as plasticizers in adhesive formulations and associated methods of use

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.
