Method for the polymerization of vinyl monomers |
| abstract |
ABSTRACT OF THE DISCLOSURE A method for polymerizing a vinyl monomer in a polymerization reactor is provided. The inner walls of the polymerization reactor and other surfaces come into contact with the monomer and are coated with an aqueous liquid containing at least one alkali metal or ammonium salt of an anionic dye of the sulfonic carboxylic acid form and having a pH value adjusted not to exceed 7 by aid of a pH adjusting agent. The thus coated surfaces are dried with heat before the polymerization is conducted. The method serves to reduce the deposition of polymer scale on those sur-faces and, consequently, improves the productivity as well as the quality of polymer product. |
