   Beispiele :
1. Man löst 100 Gewiehtsteile Chlorkautschuk und 5 Gewichtsteile p-Toluolsulfamid in 855 Ge-   wichtsteilen   Toluol oder Xylol und vermischt mit 40 Gewichtsteilen Glimmerpulver. Auf Metall, Holz oder Pappe aufgetragen, trocknet die Mischung zu einem kampfgasfesten Anstrich. 



   2. Eine Lösung von 6   Gewichtsteilen Polyacrylsäuremethylester   in 69 Gewiehtsteilen Äthylacetat und 5 Gewichtsteilen Aceton wird nach Zusatz von 20 Gewichtsteilen Glimmerpulver auf Stoff 
 EMI2.1 
 
3. Zwei Stoffbahnen werden lostsicher verklebt durch eine Emulsion aus 15 Gewichtsteilen Polyvinylacetat, 15 Gewichtsteilen eines Kondensationsproduktes nach österr. Patent Nr. 147801 hergestellt, 50 Gewichtsteilen Wasser und 20 Gewichtsteilen Talkum. 



   4. In 100 Gewichtsteilen einer wässrigen Lösung von 15 Gewichtsteilen Polyvinylalkohol werden 5 Gewichtsteile Talkum, angeteigt mit 5 Gewichtsteilen Glycerin, gleichmässig verteilt. Die Masse ergibt, auf Leder gestrichen, eine gegen Kampfgase und-flüssigkeiten beständige Imprägnierung. Durch Nachbehandlung mit Gerbstoffen wird die Wasserbeständigkeit erhöht. 



   5.100 Gewichtsteile einer alkalischen Lösung, hergestellt durch Auflösen von 10 Gewichtsteilen   Celluloseäthercarbonsäure   in Natronlauge, vermischt man mit 5 Gewichtsteilen Talkum und

   Examples:
1. 100 parts by weight of chlorinated rubber and 5 parts by weight of p-toluenesulfamide are dissolved in 855 parts by weight of toluene or xylene and mixed with 40 parts by weight of mica powder. Applied to metal, wood or cardboard, the mixture dries to form a chemical resistant coating.



   2. A solution of 6 parts by weight of polyacrylic acid methyl ester in 69 parts by weight of ethyl acetate and 5 parts by weight of acetone is added to fabric after 20 parts by weight of mica powder
 EMI2.1
 
3. Two lengths of fabric are securely bonded by an emulsion of 15 parts by weight of polyvinyl acetate, 15 parts by weight of a condensation product produced according to Austrian Patent No. 147801, 50 parts by weight of water and 20 parts by weight of talc.



   4. In 100 parts by weight of an aqueous solution of 15 parts by weight of polyvinyl alcohol, 5 parts by weight of talc, made into a paste with 5 parts by weight of glycerin, are evenly distributed. When painted on leather, the mass results in an impregnation resistant to war gases and liquids. Post-treatment with tanning agents increases the water resistance.



   5,100 parts by weight of an alkaline solution, prepared by dissolving 10 parts by weight of cellulose ether carboxylic acid in sodium hydroxide solution, is mixed with 5 parts by weight of talc and
