Abstract
In the polymerisation of monomeric vinyl chloride, alone or mixed with one or more olefinically unsaturated, copolymerisable monomers, in the presence of a polymerisation initiator, the deposition of polymer crusts is prevented, and the quality and the productivity increased, if, before the polymerisation, the surfaces of the inside wall and other parts of the polymerisation vessel which come into contact with the monomer or the monomers are each treated with at least one compound selected from a) polar organic compounds, including polar organic dyes, and b) halides, hydroxides, oxides, and carboxylates of metals, oxygen acids of elements from the second to the sixth period of groups IIB and III to VII of the Periodic Table, and inorganic salts of these oxygen acids. The compounds a) and b) are applied separately or simultaneously, using conventional techniques.
