Kind Code:
B2
Abstract:
A method for preparing polymers of vinyl chloride in which polymerization of the corresponding monomer or monomers is carried out in microsuspension in the presence of a seeding product in the form of a dispersion of particles of a vinyl polymer previously prepared by polymerization in microsuspension, the particles of which contain at least one organic soluble initiator, without any complementary addition of initiator and in the presence of one or more other seeding products in the form of dispersion of vinyl polymer, the sizes of which differ from one another and from the particles of the first seeding product.
