Abstract

Storable polychloroprene adhesives can be produced by polymerizing chloroprene in a manner known per se in the presence of a dialkylxanthogen disulphide reacting 50 to 90% of the monomer and dissolving the polymer thus obtained in an organic solvent to obtain viscosities in the range of 10 to 100 poises.
