Disclosed are multi-purpose alkali-swellable and alkali soluble
associative polymers, which are the polymerization product of a monomer
mixture comprising: (a) at least 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 from the group
consisting of a second associative monomer having a second hydrophobic
end, a semihydrophobic monomer and a combination thereof; and,
optionally, (e) one or more crosslinking monomers or chain transfer
agents. When monomer (d) is an associative monomer, the first and second
hydrophobic end groups of monomers (c) and (d) have significantly
different hydrophobic and/or steric character from one another. The
multi-purpose associative polymers surprisingly provide desirable
Theological and aesthetic properties in aqueous media.
