ABSTRACT:
A process for polymerizing chloroprene which may contain as much as 50% by weight of a copolymerizable monomer, in an alkaline aqueous emulsion, of which the alkali ions at least partially consist of potassium, into a latex rich in solid matter having a solid content of from 50 to 65% by weight in the presence of an alkali salt of disproportionated abietic acid and a formaldehyde condensate with naphthalene sulphonic acid and also an alkali hydroxide, whereby polymerization is carried out until there is a conversion of more than 90% characterized in that
