ABSTRACT:
A copolymer comprised of at least one monomer having ethylenic unsaturation and a carboxylic acid group, optionally at least one monomer having ethylenic unsaturation and not having a carboxylic acid group, at least one oxyalkylated monomer having ethylenic unsaturation and terminated by a fatty hydrophobic chain having at least 26 C atoms, and optionally at least one monomer having at least two sites of ethylenic unsaturation. The copolymer is employed as a modifier of rheological properties, stabilizing agent, and/or an antisedimentation or suspension agent for coarse mineral or organic materials, in applications such as drilling muds, textile printing pies, cosmetics, detergents, plant protection, and paints and coatings.
