Abstract
Adding a compatible high melt flow rate (MFR), low melt viscosity, hydrogenated styrene block copolymer to amorphous poly alpha-olefins (APAOs) results in adhesives that show acceptably high elongation and tensile strength, and which, when applied by different hot melt application methods onto elastic strands, result in personal hygiene article components that perform comparably to such components assembled using just styrene block copolymer components formulated with compatible tackifiers, processing oils and other additives.
