Beschreibung
Zusammenfassung:	The aim of the invention is to simplify the production of conventional rubber adhesives based on stabilized polyvinyl acetate dispersions and to improve the drying and adhesive properties thereof. To these ends, the concentration of the protective colloid polyvinyl alcohol or starch ether is increased without adding an aqueous polymer solution of polyvinyl alcohol or dextrin. Adding an interfacially active substance accelerates the activation of the adhesive after drying the same at temperatures above 160 DEG C.
