Abstract
The invention relates to compositions comprising two structured linear copolymers selected from the group consisting of block copolymers and gradient copolymers, these copolymers being prepared by different controlled polymerization techniques and the difference in the polydispersities of these copolymers, Δ(M/M), being ≧0.25. The invention further relates to the production of such blends and to their use as wetting agents and dispersants.
