ABSTRACT:
A process for producing an elastomer-filler mixture optionally containing an extender oil, comprising the combined precipitation of a homogeneous mixture of a synthetic elastomer latex, produced by emulsion polymerization in an anionic emulsifier system, and an aqueous suspension of a silicic acid based filler, using an acid and, optionally, an electrolyte or other flocculant; separation of the precipitated mixture; and drying of the mixture; is improved in that the filler suspension contains 0.1-5% by weight, based on the amount of filler, of a copolymer of acrylamide and dimethylaminoethyl methacrylate.
