ABSTRACT:
It has been found that monovinylidene aromatic/conjugated diene/ethylenically unsaturated acid copolymer compositions are provided with good combinations of physical properties when a sulfoalkyl monomer is employed in minor amounts in such polymer in place of emulsifying additive(s). In particular, the combinations of wet and dry pick resistance have been shown to be maintained or improved when paper coating formulations are prepared from latex polymer compositions according to this invention. Sulfoalkyl (meth)acrylate salts and 2-acrylamido-2-methylpropane sulfonic acid salts are shown to be suitable sulfoalkyl monomers for this purpose.
