PROCESS FOR THE PRODUCTION OF FLUID AQUEOUS DISPERSIONS OF POLYMERS OF CONJUGATED DIENES Abstract of the Disclosure This invention relates to a process for the production of an aqueous dispersion based on homo- and copolymers of conjugated dienes which is fluid under normal conditions and has a solids content of from 25 to 55%, by weight, and an average latex particle diameter of from 20 to 150 nm, characterised in that in an aqueous dispersion based on homo- and co-polymers of conjugated dienes which has been produced by one of the conventional processes and is not fluid under normal conditions and is free from alkane polysulphonate salts, from 0.05 to 0.5%, by weight, based on the solids content of the dispersion, of a water-soluble salt of at least one alkane polysulphonate is uniformly distributed in the form of a dilute aqueous solution and is dissolved in the aqueous phase of the dispersion.
