Abstract
PURPOSE: To prevent scale deposits and corrosion of the inner walls of a polymerizer, etc. due to chloride ions, etc., by making the surfaces of the inner walls of the polymerizer and/or polymerizer apparatuses in contact with the monomer from specific two-phase stainless steel.
CONSTITUTION: Vinyl chloride monomer or its mixture with other copolymrizable monomers is radically polymerized in the presence of a radical polymerization catalyst in an aqueous medium at 40W80°C, using polymerization equipment, wherein the surface of the inner walls of polymerizer and/or polymerizer apparatuses in contact with the monomer are partly or wholly made from two-phase stainless steel consisting of ferrite and austenite phases, and planished so that the relative-specular glossiness measured according to the method 2 specified under JIS-Z-8741-1962 (the glossiness of a reference silver metallized mirror is regarded as 100%) may be 70% or more.
