Abstract

Ces déchets consistent en résidus de réacteur de polymérisation ou de copolymérisation de chlorure de vinyle, bouteilles non consignées, etc... On broie finement ces déchets, puis on mélange intimement la poudre fine obtenue avec un ou des plastifiants et éventuellement avec un ou des lubrifiants et d'autres constituants classiques de mélanges pour masses plastiques de PVC, et on répartit ce mélange en nappes que l'on chauffe à une température inférieure ou égale à température normale de gélification, ce qui conduit à un PVC ou copolymère de chlorure de vinyle régénéré utilisable de façon connue en soi. Les plaques ou bandes de PVC ou de copolymère de chlorure de vinyle obtenues à la sortie du four peuvent, après granulation, être transformées par moulage en produits serai-finis ou finis pour tout emploi qui nécessite un PVC plastifié ou légèrement plastifié, par exemple en semelles de chaussure, pots de fleurs, etc.
