<p>A reaction vessel having on the internal surfaces thereof a coating containing, as a primary ingredient, a straight chain or branched polyaromatic amine made by the reaction of any one by itself, except the polyhydric phenols, or more than one, of the compounds selected from polyamino benzenes, polyhydric phenols, aminophenols, alkyl-substituted aminophenols, diphenylamines, and alkyl-substituted diphenylamines, which coating is applied to said surfaces from an organic solvent solution. Also included are the above compounds having a halogen substitution on the ring. Further, there is included the process for coating said internal surfaces whereby polymer build-up on said surfaces is substantially sliminated.</p> |
