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 60 percent by weight, based on the weight of the copolymer; and, optionally, a third monomer comprising an amine, wherein the third monomer, if present, is present in an amount of from about 0.5 percent by weight to about 5 percent by weight, based on the weight of the copolymer. A toner including the copolymer as a toner surface additive. An emulsion aggregation toner process including the copolymer as a toner surface additive.
