Abstract
The present invention relates to novel compositions comprising (a) anionic block copolymers having at least two blocks of a mono alkenyl arene and at least one block of a conjugated diene and mono alkenyl arene having a specific arrangement of the monomers in the copolymer block, and (b) tailored softening modifiers have a particular structure that results in a surprising improvement in properties for the composition. Also included are processes for the manufacturing such novel compositions and various end-uses and applications for such compositions.
