摘要： There is provided a polymer scale deposition preventive agent, comprising an alkaline solution of a condensation product having a molecular weight of 500 to 1,000,000 obtained by condensing a dimer compound of 2,3-dihydroxynaphthalene with formaldehyde. By polymerizing vinyl chloride or a monomer mixture containing vinyl chloride in a polymerization vessel wherein a coating film made of said polymer scale deposition preventive agent has been formed on the inner wall surface and the like, polymer scale is effectively prevented from depositing not only on an agitation apparatus but also on areas near the interface between a gas phase and a liquid phase, which prevention of the polymer scale deposition is conventionally difficult. Thus, a vinyl chloride polymer can be obtained which contains colored foreign matters, fish eyes, etc. in small amounts and is small in initial discoloration and is good in quality.

摘要： The invention provides a very efficient method with highly durable effect for preventing polymer scale deposition on the reactor walls and other surfaces coming into contact with the monomer during polymerization of an ethylenically unsaturated polymerizable monomer in an aqueous medium such as in the suspension polymerization of vinyl chloride. The method comprises coating the reactor walls, prior to polymerization, with a novel coating material which is a condensation product obtained by the condensation reaction of an aromatic amine compound such as aniline and an aromatic nitro compound such as nitrobenzene in the presence of a mineral acid and a specified condensation catalyst. It is sometimes preferable that the condensation product is basified or treated with an alkali or ammonium compound to be imparted with a modified solubility behavior.

摘要： The invention provides a novel method for preventing polymer scale deposition on the reactor walls in the polymerization of vinyl chloride, vinylidene chloride, styrene and other ethylenically unsaturated monomers in an aqueous medium. The inventive method comprises coating the reactor walls, piror to polymerization, with an aqueous coating solution containing a water-soluble ionic polymer and a water-soluble ionic dye having counteractive polarity to the polarity of the water-soluble ionic polymer compound. In other words, a water-soluble anionic dye is used as combined with a water-soluble cationic polymer and a water-soluble cationic dye is used as combined with a water-soluble anionic polymer compound. The scale preventing effect obtained with the combined use of the above two components can be further increased when the aqueous coating solution is admixed with a monovalent alcohol having from 3 to 6 carbon atoms in a molecule owing to the improved spreading of the aqueous solution on the metal surface of the reactor walls. The effect of the method is so remarkable and reliable that polymerization of styrene and other monomers can be performed in a stainless steel polymerization reactor, said polymerization being hitherto conducted in a glass-lined reactor due to the lack of an efficient method for preventing polymer scale deposition on the stainless steel surfaces.
