摘要: Accordingly, the invention provides a process for the preparation of an artificial latex, comprising the steps: (a) emulsification of a cement comprising a rubber dissolved in a suitable organic solvent, together with an aqueous surfactant solution, thus forming an oil-in-water emulsion; (b) step-wise reduction of the solvent content of the oil-in-water emulsion in two or more stages resulting in an artificial latex. In addition, the invention provides a continuous stirred vessel for removing an organic solvent from an oil-in-water emulsion comprising rubber dissolved in an organic solvent.
