Abstract

PURPOSE: Cellulose or its derivative is previously coated on the inner wall of a vinyl chloride monomer polymerizer, thus preventing the build-up of the polymer on the inner walls without any adverse effect on the polymrization.
CONSTITUTION: The inner walls or parts of polymerizer, which contact with vinyl chloride monomer when vinyl chloride monomer alone, or a mixture thereof with other copolymerizable monomers is polymerized in an aqueous medium or bulk state, are coated with cellulose or its derivative previously. The coating is effected by using its aqueous solution or other solution as in an aqueous alkali, aqueous salt, cupric ammonia, organic solvent. The prevention of the build-up of polymer is supposed to be caused by the polar groups of hydroxyl or other in cellulose functioning as hydrophilic groups.
