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.
