IPC: B01F27/73
Filed: 1981-05-30
Granted: 1984-10-19
Abstract: Continuous polymerization of a liq. polymerization medium to obatin fine particles of a solid product is effected by conducting the reaction in a polymerization reactor. Mixing is effected by elliptically shaped paddles mounted on two rotating shafts. which are enclosed by the walls of the reactor vsssel. The shafts rotate in opoosite directions and at a 90deg. phase differencd so that the major axis of one elliptical paddle approaches the minor axis of the other. This also gives a longgitudinal shearing action across a notional interface between the two shafts. Process is particularly useful for continuous polymerization of trioxane or with ethylene oxide, dioxolane, butanediol, and etx.
