Hydrophobically modified polymers and its use as dispersant and for preventing scale

摘要

Hydrophobically modified polymers for use as anti-sealant and dispersant. The polymers are useful in compositions used in aqueous systems. The polymers include at least one hydrophilic acid monomer, wherein the at least one hydrophilic acid monomer is a polymerizable carboxylic acid or sulfonic acid functionality but not both. The polymers also include at least one hydrophobic moiety. A solvent-free process for preparing these polymers is also provided.
