Abstract

PURPOSE: To obtain uniform acrylonitrile polymer, by effecting the aqueous precipitation polymerization of acrylonitrile, using energy due to the high-speed revolution of a circulating pump impeller for the mixing energy of the reaction mixture.
CONSTITUTION: Aqueous precipitation polymerization of acrylonitrile is carried out by using energy due to the high-speed revolution of a circulating pump imepller for circulation of the mixture to the tank type reactor with agitating blades for fluid mixing energy. The monomer may be acrylonitrile alone or a combination of 50wt% or more of acrylonitrile and copolymerizable monomers. As for the copolymerizable monomers, vinyl acetate, ethyl (meth) acrylate, vinyl chloride, acrylamide, (meth) acrylic acid, etc. may be cited.
