Abstract

Appareillage pour la photopolymérisation continue de monomères à insaturation éthylénique. Cet appareillage consiste en réacteurs individuels 1, 14 groupés par stades opératoires et consistant chacun en un cylindre de verre fermé éclairé de l'extérieur par des lampes et équipé à l'intérieur par un agitateur et un échangeur de chaleur, le cylindre étant irradié de l'extérieur par la lumière qui déclenche la polymérisation, et la chaleur amenée de l'intérieur ou évacuée vers l'intérieur sous mélange constant. L'appareillage selon l'invention permet de pratiquer des photopolymérisations à l'échelle industrielle.
