Abstract

A process for the preparation of a vinyl halide polymer of small particle size, by bulk polymerization, comprising the following steps: (1) subjecting to polymerization meeting a monomeric composition comprising a monomeric vinyl halide or a combination of a monomeric vinyl halide with an ethylenically unsaturated comonomer copolymerizable therewith, in a first step, using a high stirring speed at a temperature of between about 30 and 70, in the presence of an additive selected from the group consisting of: a) an inert material, organic or inorganic, of fine particle size, which is solid at least at the reaction temperature and insoluble in said monomer, said material having an average particle size comprised between about 0.001 and 50 microns and being present in a proportion of 0.001 to 5% by weight, calculated on the monomer composition rich present in the first stage, b) a surfactant in a proportion of 0.01 to 5% by weight, calculated on the monomer present in the first stage; c) a combination of said inert material of fine particle size and the surfactant mentioned and d) a polyolefin in a proportion of about 0.05 to 4% by weight, calculated on the monomeric composition present in the first stage; until about 3 to 20% by weight of said monomeric composition has become polymer particles.
