Abstract
A monomer compound that contains at least one polymerizable functional group per molecule, and at least one bicycloheptyl-, bicycloheptenyl-, or branched (C5-C42)alkyl-polyether radical per molecule, wherein the bicycloheptyl- or bicycloheptenyl-polyether radical may optionally be substituted on one or more of the ring carbon atoms by one or two (C1-C6)alkyl groups per ring carbon atom is useful in making polymers, particularly pH responsive polymers.
Claims7

- a) a latex polymer,
- b) a pH responsive polymer comprising, based on the total weight of monomers,
- (i) from about 25 to about 70 percent by weight acid monomeric units, each independently comprising a carboxylic acid-functional substituent group,
- (i) from about 30 to about 70 percent by weight nonionic monomeric units, each independently comprising a nonionic substituent group, and
- (iii) from about 0.05 to about 20 percent by weight hydrophobic monomeric units, each independently derived from a monomer according to structure (XXI) or structure (XXII):
- and
- c) an emulsifier, and
- d) water.
