ABSTRACT:
A novel polymer of a vinyl benzyl ether monomer and at least one other copolymerizable monomer, at least one of which other monomers has a carboxylic acid group, an anhydride group, a sulfate group, a sulfonate group or a hydroxyl group is disclosed. The vinyl benzyl ether monomer has the formula ##STR1## wherein R is hydrogen or methyl, m is about 10 to 100 and Y is --OR.sub.1, --SR.sub.1, ##STR2## where R.sub.1 is an alkyl, aralkyl or alkaryl hydrophobic group of 10 to about 22 carbon atoms, R.sub.2 is an alkyl group of 1 to about 22 carbon atoms and R.sub.3 is hydrogen or an alkyl group of 1 to about 22 carbon atoms, provided R.sub.2 and R.sub.3 in combination have at least 10 carbon atoms.
