Abstract
The invention relates to a process for the preparation of an aqueous dispersion of halogenated vinyl polymers by polymerization, according to which, after polymerization, a basic agent is added in an amount such that the pH of the aqueous dispersion is less than approximately 5. The invention also relates to the aqueous dispersion obtained, which can be coated onto polymeric substrates made of paper or of regenerated cellulose.
