Abstract
Procedure and autoclave for the mass preparation of polymers and copolymers based on vinyl chloride, in two stages carried out in different facilities, the process being characterized in that in a first stage, called prepolymerization, a limited polymerization is carried out, with stirring of high turbulence, until a degree of conversation of the monomer or monomers of the order of 7 to 15% is obtained, and then, in a second stage, a final polymerization operation is carried out, in an autoclave, under slow stirring speed, however, this stirring speed remains sufficient to ensure good thermostatization of the reaction medium until the end of the polymerization or copolymerization reaction.
