Abstract
This invention relates to latex polymers and blends of such latex polymers used to produce articles having superior electrostatic dissipative properties. The polymers and blends comprise one or more (1) polymers, in latex, or dispersion form, of (a) at least one reactive macromer of at least one alkylene oxide having at least one functional group capable of free-radical transformation, (b) optionally, at least one ethylenically unsaturated monomer having at least one carboxylic acid group, and (c) optionally, one or more free radically polymerizable comonomers, and (2) one or more other polymer latexes or dispersions of such polymers as natural rubber, conjugated-diene-containing polymers, hydrogenated styrene-butadiene triblock copolymers, chlorosulfonated polyethylenes, ethylene copolymers, acrylic and/or methacrylic ester copolymers, vinyl chloride copolymers, vinylidene chloride copolymers, polyisobutylenes, polyurethanes, polyureas, and poly-urethane-urea)s.
