Abstract
The present invention relates to a process for seeded microsuspension polymerization of vinyl chloride in aqueous medium under the action of at least one organosoluble initiator, at least one reducing agent and at least one water-soluble metal salt in the presence of at least one fatty acid alkali metal or ammonium salt. It also relates to the polymers obtained in this way which are suitable for giving plastisols having specific properties.
