摘要：Disclosed are multi-purpose alkali-swellable and alkali soluble associativepolymers, which are the polymerization product of a monomer mixture comprising: (a) atleast one acidic vinyl monomer; (b) at least one nonionic vinyl monomer; (c) a first

associative monomer having a first hydrophobic end group; (d) a monomer selected fromthe group consisting of a second associative monomer having a second hydrophobic end,a semihydrophobic monomer and a combination thereof; and, optionally, (e) one or morecrosslinking monomers or chain transfer agents. When monomer (d) is an associativemonomer, the first and second hydrophobic end groups of monomers (c) and (d) havesignificantly different hydrophobic and/or steric character from one another. The multi-purpose associative polymers surprisingly provide desirable rheological and aestheticproperties in aqueous media.
