Description


Disproportionated rosin is probably the most frequently utilized technology for preparing rubber emulsifiers, resin dispersions, and other uses requiring a low content of abietic acid cut off from supplies of natural rubber and the chemical industry was called upon to develop technology for synthetic rubbers. The continuing need for synthetic rubber led to the development of emulsion polymerization. Hercules developed disproportionated wood rosin wherein the diene isomers were converted primarily to dehydroabietic and dihydroabietic acids. Specially treated or refined tall oil, which is about one- half rosin and one-half fatty acid, also is used as an emulsifier in competition with the rosin/fatty acid soap emulsifiers. Today, disproportionated rosin and its derivatives are manufactured on a global basis. The disproportionated rosin product is utilized not only as an SBR polymerization emulsifier, but is also widely used in emulsion polymerization of ABS (acrylonitrile butadiene styrene) elastomers. It is the yellowish brittle solid dissolved in toluene, gasoline and other organic solvents.
