"A process for the production of synthetic rubber la- tices, their use as a starting material in the production of pressure-sensitive adhesives and pressure-sensitive adhesives" ABSTRACT OF THE DISCLOSURE A process for the production of synthetic rubber latices by the emulsion polymerisation of a monomer mixture of: 40 to 80 parts by weight of a conjugated diene; 0 to 45 parts by weight of an aromatic vinyl compound; 0 to 30 parts by weight of (meth)acrylonitrile 0 to 30 parts by weight of a (meth)acrylic acid ester containing from 1 to 12 carbon atoms in the alcohol component or other copolymerisable compounds, and 0.5 to 5.0 parts by weight of an .alpha. ,.beta.-unsaturated monocarboxylic or dicarboxylic acid, the sum of the monomer components amounting to 100 parts by weight, characterised in that from 0.5 to 2.0 parts by weight of a chain transfer agent are used per 100 parts by weight of monomer. Said latices can be used for producing pressure- sensitive adhesives.
