    摘要: A process of producing an artificial latex, comprising the steps: (a) cement formation, wherein a rubber is dissolved in a suitable hydrocarbon solvent; (b) emulsification of the cement formed in step (a), together with an aqueous soap solution, thus forming an oil-in-water emulsion; (c) hydrocarbon solvent removal, resulting in a latex of the rubber having particles of a median particle size in the range of from about 0.5 to 2.0 μm, and optionally (d) latex concentration, forming an artificial latex with a higher solids content, characterized in that in step (b) a premix is formed first, which is subsequently homogenized into an oil-in-water emulsion, and wherein the premix is formed by mixing the cement with the aqueous soap solution at a volume ratio of 1:1.5 to 1:3 using at least one homogenizer comprising a stator and a rotor, that is operated at a tip speed of the outer ring of the rotor in the range of from 8 to 16 m/s, and wherein the premix is subsequently homogenized in a rotor/stator homogenizer operated at a tip speed of the outer ring of the rotor in the range of from 16 to 35 m/s.
