ABSTRACT:
Bimodal latexes having two separate and distinct particle size distributions have high solids content, good high shear rheology and good low shear viscosity. The large size polymer particles of the bimodal latex have a heterogeneous character. These bimodal latexes, e.g., styrene/butadiene/acrylic acid/itaconic acid latexes are employed in coating paper in conjunction with a mineral filler using a coating device such as a blade coater to yield high quality, glossy coatings which can be easily applied.
