The invention relates to a comb polymer having a polymer backbone and lateral side chains linked to the polymer backbone, wherein the lateral side chains comprise a) alkyl ether terminated polyalkylene oxide side chains, and b) tertiary amine-functional side chains, wherein the tertiary amine groups are at least partly neutralized by an acid having a molecular weight in the range of 100 g/mol to 2000 g/mol, wherein the molecular weight relates to the number average molecular weight Mn in the case of polymeric acids, and wherein the lateral side chains a) and b) are distributed in random order.

Comb polymer having salt groups

The invention relates to an aqueous composition having a continuous aqueous phase, a polymer having a polymer backbone having carboxylic acid groups covalently linked to the polymer backbone, a polyalkylene oxide terminated at one end by a hydrocarbyl group having 8 to 30 carbon atoms, and, a compound according to formula (I) as described herein.

Aqueous dispersant composition

The invention relates to polyamine addition compounds, methods for the production thereof, the use thereof as crosslinking agents and dispersing agents, and paints and plastic materials containing the addition compounds.
