Method for preventing polymer scale deposition in the polymerization of ethylenically unsaturated monomers |
| abstract |
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 ehtylenically 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. |
