Patent ID: 8784786

Claim:
A polymer made by copolymerization of a mixture of polymerizable monomers, said polymerizable monomers which copolymerize to form the polymer comprising: (a) one or more first monomers each independently selected from monomers according to structure (XIII): wherein: R 19 is H or methyl, i is an integer of from 10 to 40, and j is an integer of from 1 to 20, (b) one or more second monomers copolymerizable with the first monomer, wherein: the one or more second monomers are each independently selected from monomers according to structure (XX): wherein R 21 is linear (C 5 -C 50 )alkyl, R 25 is methyl or ethyl p and q are independently integers of from 2 to 5, each r is independently an integer of from 1 to about 80, each s is independently an integer of from 0 to about 80, and t is an integer of from 1 to about 50, provided that the product obtained by multiplying the integer t times the sum of r+s is from 2 to about 100, and (c) one or more third monomers each independently selected from monocarboxylic acid monomers according to structure (XXII): R 34 —R 32 —R 31 (XXII) wherein: R 31 is a moiety that comprises a carboxylic acid, sulfonic acid, or phosphoric acid group, R 32 is absent or is a bivalent linking group, and R 34 is a moiety having a site of ethylenic unsaturation, and (d) one or more fourth monomers each independently selected from compounds according to structure (XXIV): R 43 —R 42 —R 41 (XXIV) wherein: R 41 is alkyl, hydroxyalkyl, alkoxyalkyl, cycloalkyl, aryl, aralkyl, or aryloxy, R 42 is absent or is a bivalent linking group, and R 43 is a moiety having a site of ethylenic unsaturation.
