Abstract
La présente invention a pour objet un procédé de séparation du chlorure de vinyle monomère d'un mélange aqueux de résine de chlorure de polyvinyle. Elle est caractérisée en ce qu'on fait passer le mélange aqueux de résine sur une surface vibrante, à température élevée et sous une pression inférieure à la pression atmosphérique. Elle se rapporte à un procédé d'extraction de chlorure de vinyle monomere résiduel présent dans des mélanges aqueux de résine de chlorure de polyvinyle.The present invention relates to a process for separating monomeric vinyl chloride from an aqueous mixture of polyvinyl chloride resin. It is characterized in that the aqueous resin mixture is passed over a vibrating surface at elevated temperature and under a pressure below atmospheric pressure. It relates to a process for extracting residual vinyl chloride monomer present in aqueous mixtures of polyvinyl chloride resin.
