Abstract
The invention relates to a composition containing a polymer obtained by polymerising (1) a mono-vinyl monomer with one or more carboxylic acid groups to form a polymer with at least 2 to 200, or 5 to 150, or 10 to 100, or 15 to 50 repeat units, and (2) reacting the polymer of (1) with a primary hydrocarbyl amine and polyoxyalkylene primary amine (typically polyetheramine). The invention further relates to a composition containing a particulate solid, a liquid medium, and the polymer. The invention further relates to the use of the polymer as a dispersant.
