Abstract

A monomer compound that contains at least one polymerizable functional group per molecule, and at least one bicycloheptyl-, bicycloheptenyl-, or branched (C 5 -C 42 )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 (C 1 -C 6 )alkyl groups per ring carbon atom is useful in making polymers, particularly pH responsive polymers.
