Abstract
Procédé pour la polymérisation en suspension du chlorure de vinyle avec un rendement élevé. Selon ce procédé la suspension est soutirée du réacteur avant d'avoir atteint 70 % de la conversion et elle est recyclée dans un tube externe qui est refroidi par l'extérieur et après avoir ainsi circulé dans ce tube elle retourne vers le réacteur. En modifiant d'une série d'élément solides 2 sur sa paroi interne 1 les résultats peuvent être encore améliorés. Ce procédé permet d'utiliser des réacteurs de plus grande capacité en ayant un rendement élevé.Process for the suspension polymerization of vinyl chloride with high yield. According to this process, the suspension is withdrawn from the reactor before having reached 70% of the conversion and it is recycled in an external tube which is cooled from the outside and after having thus circulated in this tube it returns to the reactor. By modifying a series of solid elements 2 on its inner wall 1 the results can be further improved. This process makes it possible to use reactors of greater capacity while having a high efficiency.
