Il a maintenant été constaté que si l'on fait réagir les

produits nouveaux contenant du soufre lié directement au carbone, utiles (éventuellement avec une addition de plastifiants convenables) à la préparation de masses plastiques ayant un module d'élasticité sensiblement supérieur à celui obtenu à. base de chlorure de polyvinyle, ainsi qu'une plus grande résistance à la cnaleur. Suivant la complexité du polyvinyle et les proportions entre le polysulfure et les halogénures de polyvinyle, on obtient des produits de propriétés différentes, de sorte qu'il est possible de préparer, suivant la présente invention, des produits excellents susceptibles de servir aux emplois les plus variés.

  
Les russes plastiques peuvent être obtenues également en présence de diluants solides inertes*

It has now been observed that if the

new products containing sulfur bound directly to carbon, useful (optionally with the addition of suitable plasticizers) in the preparation of plastic masses having a modulus of elasticity appreciably greater than that obtained at. based on polyvinyl chloride, as well as greater resistance to heat. Depending on the complexity of the polyvinyl and the proportions between the polysulfide and the polyvinyl halides, products of different properties are obtained, so that it is possible to prepare, according to the present invention, excellent products capable of serving the most important uses. varied.

  
Plastic rollers can also be obtained in the presence of inert solid diluents *
