Abstract
a. L'invention concerne un procédé de démonomérisation de dispersions de chlorure de polyvinyle ou de dispersions des co-polymérisats ou polymères greffés correspondants. b. Ce procédé est caractérisé en ce qu'on chauffe la dispersion aqueuse de chlorure de polyvinyle ou la dispersion de co-polymère greffé correspondante avec une teneur en matière solide de 15 à 64 %, pendant 10 secondes à 2 minutes, à des températures de 105 à 150 degrés C, sous une pression de 1 à 10 atmosphères des stabilisants et/ou des substances surfactives en une quantité de 0,01 à 1,0 masse %, calculé sur la teneur en matière solide de la dispersion. c. L'invention s'applique à la démonomérisation de dispersion de chlorure de polyvinyle ou de dispersion de copolymère ou polymère greffé.
