Abstract
According to the invention, vinyl chloride monomer or a monomer mixture essentially comprising vinyl chloride is polymerised in a polymerisation reaction whose internal walls and stirrer and other surfaces which come into contact with the monomer or the monomers have been coated with a mixture of at least one electron-donor compound and at least one electron-acceptor compound. This method greatly reduces the deposition of polymer crusts on these surfaces, and a high-quality polymer can be produced.
