Abstract
An aqueous coating solution is sprayed into the interior of the reactor. After the aqueous coating solution has been sprayed, steam is injected and condensed within the reactor. Upon polymerizing a vinyl chloride-base monomer composition in the reactor after having been treated, the formation of deposits of polymer on the internal surfaces of the reactor is substantially reduced and even suppressed.
