Apparatus for centrifugal thin film polymerization

Abstract

Abstract PURPOSE:The titled polymerization apparatus having a sprinkling nozzle for cooling water, etc. and a rotational polymerization vessel with a rising and lowering polymer chopper in a container case having a jacket with a monomer solution feed pipe, capable of polymerizing the monomer in a wide range of concentration, and easily removing the heat of polymerization. CONSTITUTION:A rotary vessel 1 is installed in a container case 2 having a jacket 6 with a monomer soln. feed pipe 4 on the top of the case 2, and a nozzle 3 for sprinkling warm or cooling water on the outer surface of the rotary vessel 1 is provided to the inner surface of a container case 2 to control the temp. of the vessel 1. A monomer solution, e.g. acrylamide, is fed to the apparatus, and the interior of the apparatus is replaced with nitrogen gas fed from a nitrogen gas port 11. Centrifugal thin film polymerization is carried out while rotating the rotary vessel 1 to give the aimed thin film cylindrical polymer 10 on the inner surface of the vessel 1. The resultant polymer 10 is then chopped by rising and lowering a chopper 5, and closing plugs 7 are then opened to take out the polymer 10 from polymer discharging holes 8.
