Abstract
A process for the production of synthetic rubber latices by the emulsion polymerization of a monomer mixture of: PA1 40 to 80 parts by weight of a conjugated diene; PA1 0 to 45 parts by weight of an aromatic vinyl compound; PA1 0 to 30 parts by weight of (meth)acrylonitrile PA1 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 copolymerizable compounds, and PA1 0.5 to 5.0 parts by weight of an .alpha., .beta.-unsaturated mopnocarboxylic or dicarboxylic acid, the sum of the monomer compounds amounting to 100 parts by weight, characterized 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.
