Abstract

Vinyl (co)polymers which are insoluble in the monomer composition are prepared by making a fine dispersion of an aqueous solution of the catalyst in the monomers and polymerising. In particular vinyl chloride is (co)polymerised. Particle size is 0.1 to 500 mu, esp. 0.2 to 200 mu, and the particles have a high apparent density. Fast extrusion speeds may be used.
