Synergistic polymer blend dispersants, dispersant concentrates, conductive carbon dispersions, and electrode slurry compositions, and methods of making and use thereof

Abstract

Polymer blends having an organic nitrile-based copolymer, and a phenol-based polymer or a phenol-based copolymer. The organic nitrile-based copolymer has structural units comprising the residue of a substituted or unsubstituted, unsaturated organic nitrile monomer, and structural units comprising the residue of a substituted or unsubstituted, conjugated diene monomer. The phenol-based polymer has structural units comprising the residue of a substituted or unsubstituted, unsaturated phenolic monomer. The phenol-based copolymer has structural units comprising the residue of a substituted or unsubstituted, unsaturated coupled phenolic resin. The organic nitrile-based copolymer is present in an amount from about 0.5 wt % to about 99.5 wt %, and the phenol-based polymer, or the phenol-based copolymer, is present in an amount from about 0.5 wt % to about 99.5 wt %, based on the total weight of the polymer blend. The polymer blends are effective as synergistic dispersants.
