et le fumarate de diéthyle, le chlorure et le fluorure de vinylidëne. Ces  plastisols contiennent des plastifiants. Les systèmes contenant les 

  
plastifiants les plus coûteux, lesquels consistent essentiellement en des 

  
 <EMI ID=5.1>   <EMI ID=6.1> 

  
de paraffines chlorées ou de plastifiants à base d'hydrocarbures. Ces plastifiants moins coûteux nécessitent l'emploi d'agents moussants plus solubles pour obtenir une bonne stabilité de moussage. On emploie à cet effet, des agents moussants contenant de 3 à 4 % en poids de groupes hydroxyles lies au silicium. Les formulations contenant ces plastifiants moins coûteux et de grandes quantités de matière de charge sont en pratique les plus intéressantes économiquement parlant. Malheureusement, les mousses réalisées à partir de ces formulations et contenant les agents moussants précités, présentent l'inconvenant d'une structure cellulaire extrêmement grossière par comparaison avec celle des mousses fabriquées à partir de formulations contenant les plastifiants les plus coûteux.

  
La Demanderesse a maintenant, trouvé que cet inconvénient pouvait être pallia par l'incorporation à la formulation, d'une certaine quantité de silice hydrophobe finement divisée.

  
La présente invention concerne donc des plastisols à base de polychlorures de vinyle pour la fabrication de mousses comprenant un homopolymère du chlorure de vinyle ou un copolymère du chlorure de vinyle et en proportion mineure;, d'un ou de plusieurs autres monomères vinyliques polymérisables, un agent moussant du type silicone de formule générale

A la fin du cycle de mélange, la mousse obtenue a été versée dans un bol d'un volume connu, l'excès &#65533;tant écrémé et le poids spécifique de la moussa non gélifiée (p non gélifié) calculé d'après le poids d'un volume connu de la mousse. 

  
Le reste de la mousse a été versé dans un moule en aluminium d'environ

le moule a été enlevé du four et refroidi à la température ambiante. La mousse a été enlevée de ce moule et la densité à sec mesurée en pesant une
