Beschreibung
Zusammenfassung:	The invention relates to a process for the prevulcanisation of natural rubber and synthetic rubber using sulphur in aqueous solutions and to the production of rubber articles from latex pre-vulcanised by this process. The vulcanisation system comprises exclusively water-soluble constituents and is added in the form of aqueous solutions to the latex, the degree of vulcanisation achieved, determined by the swelling of the dried rubber film in a suitable solvent, by the method of Murray, is 20 - 200%.
