Abstract
A polymeric composition including a copolymer comprising a first monomer having a high carbon to oxygen ratio of from about 3 to about 8; a second monomer comprising two or more vinyl groups, wherein the second monomer is present in the copolymer in an amount of from greater than about 8 percent by weight to about 40 percent by weight, based on the weight of the copolymer; and optionally, a third monomer comprising an amine, wherein the third monomer is present in an amount of from about 0.1 percent by weight to about 1.5 percent by weight, based on the weight of the copolymer; and a surfactant, wherein the surfactant has a minimum surface tension at critical micelle concentration of less than about 30 mN/m. A toner including the copolymer as a toner surface additive. An emulsion aggregation toner process including the copolymer as a toner surface additive.
