Abstract
Procedure for the mass production of polymers and copolymers based on vinyl chloride, characterized in that all or part of the polymerization or copolymerization operation is carried out, in the presence of at least one polymerization initiator with a half-life of less than one one hour at the polymerization temperature, by introducing, in the reaction medium, first of a fraction A of said polymerization initiator, and then of solution B, in at least one of the monomers, of a complementary fraction of said initiate polymerization, continuously injected in finely divided form.
