摘要：
According to a method of the present invention for producing a CPVC resin, the method includes the steps of: introducing chlorine into a slurry of a PVC resin in a first tank; transferring, from the first tank to a second tank, the slurry into which chlorine has been introduced; and irradiating, with UV light, the slurry in the second tank. This method improves an amount of chlorine dissolved into the slurry of the PVC resin and consequently, improves production efficiency of the CPVC resin.
