Improved adhesives are provided through the use of styrenic radial block copolymers, containing at least 40 wt % diblock copolymers, the adhesives have improved adhesive properties and a reduced elastic behavior 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.

Radial block copolymers and adhesives based thereon with improved die-cutting performance

The use of a polyalphaolefin oil or combinations of polyalphaolefin oils to modify the softening point characteristics of a tackifier and compositions containing a tackifier and polyalphaolefin oil are disclosed herein.

Combinations of tackifier and polyalphaolefin oil

This invention relates generally to linear tetrablock copolymer compositions and their use in road marking applications. These tetrablock copolymers contain polystyrene, polyisoprene and polybutadiene components. Road marking compounds prepared from these copolymers further contain a hydrocarbon resin.
