A series of resins were synthesized using a range of bio-based materials to control the molecular architecture, and therefore the properties, of the inventive resins. The resins were formulated into toner formulations such as those useful in printers and copiers.

Bio-based toner

A method for preparing thermoplastic toner resins is disclosed and the toner resins produced by said method. More particularly, an emulsion polymerized resin, constituting a high molecular weight component, is used as a seed for subsequent suspension polymerization of a lower molecular weight component. The emulsion micelles are swelled with monomers and subsequent suspension polymerization produces particles where the high and low molecular weight components are interpenetrated to form a resin with a bimodal distribution of molecular weight. A toner composition is made using the resin as the main component. The resin particle has a first resin portion having a particle size in the range of about 50 to about 200 nm. and a number average molecular weight in the range of about 10,to about 10,, and a second resin portion formed around the first resin portion with a number average molecular weight lower than that of said first resin portion, the resin having a polydispersity in the range of 5 to 50.

A carrier composition is provided for electrophotographic development. Core particles are coated with a graft copolymer of a fluoropolymer and methyl methacrylate. The core particles preferably are a material selected from steel, nickel, iron, ferrites, passivated iron, or mixtures or alloys thereof. The fluoropolymer preferably is a polymer selected from chlorotrifluoroethylene, polyvinylidene fluoride, polytrifluoroethylene, polytetrafluoroethylene, copolymers of vinylidene fluoride and hexafluoropropylene, and copolymers of vinylidene fluoride and tetrafluoroethylene. In a preferred carrier composition, the coating consists of two layers. The exterior layer is a graft copolymer made of a fluoropolymer and methyl methacrylate.
