Beschreibung
Zusammenfassung:	The invention is directed to a process for preparing a sealant and adhesive useful, e.g., in double glazing systems. The sealant comprises 20-80 weight percent epoxidized natural rubber, 5-30 weight percent of at least one further epoxy compound, and, as a crosslinking agent, a polyamine or polymercaptan carrying trialkoxysilyl groups. The crosslinking agent is incorporated into the epoxidized natural rubber in one step.
