<p>Improved adhesives are provided through the use of styrenic radial block copolymers, containing at lest 40 wt % diblock copolymers, the adhesives have improved adhesive properties and a reduced elastic behaviour under die-cutting conditions. Compared to conventional linear block copolymers of similar molecular weight, radial copolymers offer higher holding power and lower melt viscosity for the adhesive. They therefore contribute to an improved balance between processability and end-use properties.</p> |
