| 摘要 |
The invention relates to a process for the production of an aqueous dispersion, fluid under normal conditions, based on homo- and co-polymers of conjugated dienes and having solids contents of from 35 to 55%, by weight, and average particle diameters of from 20 to 150 nm from an aqueous dispersion based on homo- and co-polymers of conjugated dienes which has been obtained by conventional methods, is fluid under normal conditions and does not contain alkane polysulphonates, having a solids content of from 25 to 35%, by weight, and average particle diameters of from 20 to 150 nm by concentration in the presence of a water-soluble salt of at least one alkane polysulphonate.
