    摘要： A process for the preparation of an aqueous rubber emulsion (artificial latex), comprising the steps: (a) size reduction of the rubber, whereby granules are produces with shorter dissolving time; (b) cement formation, wherein the granules of step (a) are dissolved in a suitable hydrocarbon solvent; (c) preparation of an aqueous soap solution; (d) emulsification of the cement formed in step (b), using the aqueous soap solution prepared in step (c), thus forming an oil in water emulsion; (e) hydrocarbon solvent removal, resulting in an aqueous emulsion of the rubber, and optionally (f) emulsion concentration, forming an artificial latex with a higher solids content, wherein in step (a) the size reduction is carried out using a chopper and/or granulator characterized in that a soap is used as processing aid, preferably identical to the soap used in steps (c) and (d).

    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.
