Claims
- 1. A polymer comprising
- (a) about 0.2 to 15 mole percent of a vinyl benzyl ether monomer having the formula ##STR11## wherein R is hydrogen or methyl, m is about 10 to 100 and Y is --SR.sub.1, ##STR12## 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.
- (b) the balance to make 100 mole percent of one or more copolymerizable ethylenically unsaturated monomers provided a water solubilizing amount of at least one monomer having a carboxylic acid group, an anhydride group, a sulfate group, a sulfonate group or a hydroxyl group is present.
- 2. The polymer of claim 1 wherein m is 10 to about 40.
- 3. The polymer of claim 1 wherein the mole percent of said ether monomer is about 0.2 to 5 percent.
- 4. The polymer of claim 1 wherein the mole percent of said ether monomer ranges from about 1 to 3 percent.
- 5. The polymer of claim 1 wherein the oxyalkylene group is oxyethylene.
- 6. The polymer of claim 5 wherein m is 10 to about 40.
- 7. The polymer of claim 5 wherein the mole percent of said ether monomer is about 0.2 to 5 percent.
- 8. The polymer of claim 5 wherein the mole percent of said ether monomer ranges from about 1 to 3 percent.
