Abstract

THIS PROCESS IS A PROCESS FOR PRODUCTION OF A VINYL CHLORIDE POLYMER BY SUSPENSION POLYMERIZATION OR EMULSION POLYMERIZATION OF VINYL CHLORIDE MONOMER OR A MIXTURE OF VINY CLORIDE MONOMER WITH A VINY MONOMER COPOLYMERIZABLE WITH SAID VINYL CHLORIDE MONOMER IN AN AQUEOUS MEDIUM, CHARACTERIZED IN THAT THE POLYMERIZATION IS CARRIED OUT IN A POLYMERIZER, THE INNER WALL SURFACE AND PORTIONS OF THE AUXILIARY EQUPMENT THEREOF WHICH MAY COME INTO CONTACT WITH THE MONOMER DURING POLYMERIZATION BEING PREVIOUSLY COATED WITH A SCALING PREVENTIVE COMPRISING AT LEAST ONE SELECTED FROM DYES, PIGMENTS AND AROMATIC OR HETEROCYCLIC COMPOUNDS HAVING AT LEAST 5 CONJUGATED ? BONDS, WHILE CONTROLLING THE CHLORIDE ION CONCENTRATION IN THE REACTION MIXTURE TO NOT HIGHER THAN 100 PPM. ACCORDING TO SAID PROCESS, SCALING ONTO THE INNER WALL SURFACE OF A POLYMERIZER, ETC. DURING POLYMERIZATION CAN BE PREVENTED EFFECTIVELY AND SURELY.
