WETTING AGENTS AND DISPERSANTS BASED ON MIXTURES OF STRUCTURED COPOLYMERS

摘要

The invention relates to compositions containing two structured linear copolymers selected from the group consisting of block copolymers and gradient copolymers, said copolymers being produced according to differently controlled polymerization technologies and the difference of polydispersity of these copolymers being Delta(Mw/Mn) >= 0.25. The invention also relates to the production of such mixtures and their use as wetting agents and dispersants.
