The following experiment is indicative of the effect of the rosin polymer content upon the non-gelling characteristics of the resulting resinate when dissolved in,a petroleum solvent or the like. DE DEA1 en However, a natural rosin, or a high acid value disproportionated rosin, or a high acid value hydrogenated rosin requires a higher percentage of calcium resinate as stabilizer; a heat treated rosin requires a lower percentage, and a catalytically polymerized rosin requires no calcium resinate as a stabilizer. Azelaic acid is produced by a chemical synthesis pathway from oleic acid. The toner particles may have a weight average molecular weight Mw in the range of from about 2, to about 60, daltons, a number average molecular weight Mn of from about 1, to about 18, daltons, and an MWD a ratio of the Mw to Mn of the toner particles, a measure of the polydispersity, or width, of the polymer of from about 1. Oliver, and Edwin Edelstein, filed September 29, and entitled Resinlike product and process of making the same. On the other hand, when all the required monomers are added up front bulk addition instead of using a macromer formation step, more side reactions occur resulting in a darker resin color and early termination of polymer chain occurs, resulting in very low molecular weights. It is used in lacquersvarnishesand soapsand for the analysis of resins and the preparation of metal resinates. Namespaces Article Talk.

    A method of forming toner particles comprising a bio-based polyester resin, the method comprising: A forming a slurry by mixing together: a an emulsion containing the bio-based polyester resin obtained from a method comprising: i obtaining a bio-based glycerol that is a transesterification product of crude vegetable oil.

    Rosin containing one or more of these resin acids may be reacted as disclosed hereinbelow with a zinc compound to form the corresponding zinc-resin acid.

    The acid-catalyzed dimerizations of abietic acid, isopimaric acid, and gum rosins were studied. Catalysts include sulfuric acid, aluminum chloride, zinc chloride. allergic contact reactions to rosin and to determine whether such an effect might be due to tration of abietic acid in the adhesives was determined with HPLC.

    Our permanently refusible resin-like products impart added properties of hardness, through drying, gloss, improved pigment dispersion and other valuable characteristics to varnish, enamels, inks and similar coatings.

    The novel resinates of our invention have physical properties resembling those of typical resins, being characterized, for instance, by a conchoidal fracture. Bisphenol A has been identified as a carcinogen and an endocrine disrupter that causes adverse developmental health effects.

    Throughout this specification and in the claims, where percentages are referred to, percentages by weight are intended unless otherwise specifled. The second step of the polymerization results in a polymeric material having very similar properties to two BPA-containing resins produced by known methods BPA resins 1 and 2.

    If acetic acid is used, the acid will react with the zinc compound to form the corresponding acetate which is not volatile at the reaction temperature but may decompose gradually. The following will serve as an example of carrying out the fusion process of the present invention.
