Mass manufacturing process of polymers, and copolymers based on vinyl chloride in two stages, characterized in that it consists in splitting the homopolymerization and copolymerization operations carried out in a first stage, in a facility provided with a high speed agitation device , a limited polymerization until a conversion rate of, if any, of the monomers is obtained, of the order of 7 to 15 percent and preferably close to 8-10 percent, then performing in the course of a second stage the complement of the polymerization operation in a possibly several installations provided with stirring devices capable of being dragged at a slow speed, however, said driving speed remaining sufficient to ensure a good thermostatization of the reaction medium and this until the end of the homopolymerization and copolymerization reaction .
