Abstract
Vinyl chloride (co)polymer compsns. are prepd. by polymerising vinyl chloride, opt. together with other monomers mers, in the presence of a polymsn. initiator, and of additives, e.g. plasticisers, stabilisers, antioxidants, lubricants, anti-static agents and fillers, in a reactor whose internal surfaces contacting the monomers have been pretreated before polymsn. The agents used for pretreatment are (1) a polar organic cpd. or an organic dye, and (2) a metal hydroxide, oxide, halide or carboxylate, or an oxo-acid of the 6th period of a gp. IIB, or III-VII, or a salt of these oxo-oxides. Efficient preventing of polymer deposits on the internal surfaces of the reactor, in the presence of a wide range of additives. Polymer yields are not reduced.
