Abstract
Non-aqueous suspensions of water-soluble polymers may comprise water-soluble polymers selected among polysaccharides, derivatives of polysaccharides, and mixtures thereof and may further comprise a carrier fluid, an emulsifier, and a suspending agent. The suspending agent may be obtained by polymerization of: (I) from 20 to 70% by weight of a monoethylenically unsaturated monomer containing a carboxylic group; (II) from 20 to 70% by weight of a (meth)acrylic acid ester; (III) from 0 to 3% by weight of a polyethylenically unsaturated monomer; and (IV) from 0 to 10% by weight of a nonionic acrylic associative monomer. The sum of I and II may represent at least 80% by weight of the monomer mixture.
