Abstract
Polymerization of chloroprene in an alkaline aqueous emulsion provides an improved latex by adding a specific amide to the emulsion, the amide being insoluble in water, soluble in the chloroprene and not being hydrolyzed by NaOH. The presence of an amide of this type makes it possible to obtain polychloroprene latices stabilized against ageing.
