PENDING APPLICATIONS AND PATENTS
Illustrated in U.S. Pat. No. 5,945,244; U.S. Ser. No. (09/140,524; U.S. Ser. No. 09,140,594; and U.S. Pat. No. 5,935,750; all filed concurrently herewith, and the disclosures of each of which are totally incorporated herein by reference, are carrier particles comprised, for example, of a core with coating thereover of polystyrene/olefin/dialkylaminoalkyl methacrylate, polystyrene/methacrylate/dialkylaminoalkyl methacrylate, and polystyrene/dialkylaminoalkyl methacrylate. More specifically, there is illustrated in U.S. Pat. No. 5,945,244 a carrier comprised of a core, and thereover a polymer of styrene, an olefin and a dialkylaminoalkyl methacrylate; in copending application U.S. Ser. No. 09,140,524 a carrier composition comprised of a core and thereover a polymer (1) polystyrene/alkyl methacrylate/dialkylaminoethyl methacrylate, (2) polystyrene/alkyl methacrylate/alkyl hydrogen aminoethyl methacrylate, (3) polystyrene/alkyl acrylate/dialkylaminoethyl methacrylate, or (4) polystyrene/alkyl acrylate/alkyl hydrogen aminoethyl methacrylate; in copending application U.S. Ser. No. 09/140,594 a carrier comprised of a core and thereover a polymer or polymers of (1) methylmethacrylate and a monoalkyl aminoalkyl methacrylate, or (2) a polymer or polymers of methylmethacrylate and dialkylaminoalkyl methacrylate; and in U.S. Pat. No. 5,935,750 a carrier comprised of a core and a polymer coating containing a quaternary ammonium salt functionality.
The appropriate components and processes of the above cited copending applications may be selected for the present invention in embodiments thereof.
A process for the preparation of polymers which comprises generating a solution of water and polyvinyl alcohol with acetate groups; adding thereto a mixture of an alkali metal iodide and iodine; adding thereto initiator, and optional crosslinking agent; adding monomer, a mixture of monomers, or a monomer/polymer mixture; homogenizing, and polymerizing; and wherein there is formed an iodide/iodine/acetate complex prior to said polymerizing.
A process which comprises mixing a carrier core with a polymer core and polymer shell and wherein the polymer shell is present as a coating on said core and said polymer core, wherein said polymer core is generated by emulsification of and heating of monomer forming a seed latex; adding a portion of said seed latex to said emulsification mixture, followed by heating and adding another second portion of said seed latex; and wherein said shell is generated by emulsion polymerization of a monomer, followed by heating.
A carrier comprised of a core, and thereover a polymer coating containing antimony tin oxide with an average diameter of from about 5 to about 90 nanometers.
Carrier comprised of a core, a polymer coating, and wherein said coating contains a mixture of an alkali metal lauryl sulfate and a conductive component.
