<p>This method for producing a chlorinated vinyl chloride resin produces a chlorinated vinyl chloride resin by chlorinating a vinyl chloride resin by irradiating the inside of a reactor, into which the vinyl chloride resin and chlorine have been introduced, with ultraviolet light. The irradiation of ultraviolet light is carried out using at least one kind of light source that is selected from the group consisting of an ultraviolet LED, an organic EL, an inorganic EL and an ultraviolet laser. A chlorinated vinyl chloride resin which is suppressed in initial coloring during hot forming and/or has improved thermal stability can be provided by this method for producing a chlorinated vinyl chloride resin.</p> |
