摘要: his invention relates to the reduction of polymer buildup on inner surfaces a polymerization reactor by applying resistant coating material thereof, method or process said being subject this invention. An approximate monolayer results from thereto an aqueous organic solvent solution means steam, and preferably, superheated compound which is capable resisting thereon. As examples such materials there may be named polyaromatic amines, self-condensed polyhydric phenols, tannic acid tannates, various dyes as nigrosine, like, etc. When using steam apply material, same reaches in form melted mist. polymerizing olefinic monomers, vinyl halides, vinylidene monomers having at least one terminal CH 2 =C < grouping, mixtures presence coating, reaction vessel substantially eliminated.
