Abstract

PURPOSE: To carry out the continuous bulk polymerization of trioxane industrially and stably for a long time, by using a reactor, having a high self-cleaning property, and comprising convex lens-shaped or pseudopolygon-shaped plate paddle agitators with sharp ends.
CONSTITUTION: A liquid mixture of molten trioxane with a catalyst is continuously fed to a raw material feed inlet of a continuous agitating mixer comprising a hollow drum of cross section wherein eccentric circles of the same diameter are overlapped and parallel agitating shafts 1 and 1' in the respective centers of the circles in the long direction of the hollow drum, said agitating shafts 1 and 1' having a plurality of plate paddle agitators 4 and 4' having a cross section of convex lens or pseudopolygon inscribed in an imaginary circle at the respective apexes fixed to the agitating shafts 1 and 1' in contact with each other. The raw material mixture is polymerized while being transferred to an outlet, and the reaction product is taken out of the outlet away from the feed inlet as a powder or granule.
