More Information
Summary: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. Il est décrit une composition polymérique comprenant les éléments suivants : un copolymère composé dun premier monomère ayant un rapport élevé entre le carbone et loxygène, soit un rapport de 3 à 8 environ; un deuxième monomère comprenant au moins deux groupes vinyles présents dans le copolymère à une concentration au moins supérieure à environ 8 % du poids du copolymère, mais inférieure ou égale à 60 % du poids de celui-ci; un troisième monomère facultatif comprenant une amine qui, sil est présent, représente entre 0,5 % et 5 % environ du poids du copolymère. Il est décrit une encre en poudre comprenant le copolymère en tant quadditif de surface. Il est décrit un procédé dencre en poudre à agrégation par émulsion dans lequel le copolymère sert dadditif de surface.
