Styrene-acrylate → Styrene acrylic acid copolymer

Participants

Reaction Steps

A yellow styrene acrylate high gloss toner was prepared at a 2 liter bench scale (about 165 grams dry theoretical toner). The core toner slurry included about 221.4 grains of 42% solids of a styrene-acrylate latex, produced by emulsion polymerization (glass transition temperature (Tg) 51° C.+/−2° C.), with about 511.8 grams of deionized water, about 59.4 grams of polyethylene wax (commercially available from IGI) (about 31.3% solids) and about 54 grams of yellow pigment (Y74 from Sun Chemical Inc., about 20% solids), that were mixed together in a 2 liter plastic beaker. The slurry was then homogenized for a total of about 10 minutes with mixing at from about 3000 to about 4000 revolutions per minute (rpm) while adding in a coagulant solution, which included about 2.97 grams polyaluminum chloride and about 26.73 grams of about 0.02M nitric acid.
