ABSTRACT:
A process for the preparation of homo- and co-polymers of vinyl chloride by polymerization in seeded microsuspension, which comprises effecting polymerization in the presence of one or more seeding products in the form of dispersions of particles of polymers, the particles of at least one of the seeding products containing the initiator required for polymerization and said initiator being activated by an organosoluble metal complex and nitric acid.
