Abstract
This invention relates to a process of coating the internal surface of a polymerization reactor in order to substantially eliminate the buildup of polymer on said surfaces during the polymerization process. There is applied to the surfaces a coating composition containing a straight chain or branched polyaromatic amine dissolved in an aqueous acid solution and thereafter the coated surfaces are flushed or rinsed with water without drying the same.
Claims10
A process for substantially eliminating the buildup of polymers on the internal surfaces of a polymerization reaction vessel which comprises applying to said surfaces a coating solution comprised of a polyaromatic amine having a molecular weight in the range of about 250 to about 1000 dissolved in an aqueous acid solution, said polyaromatic amine having the structure ##STR2## wherein R is H or NH.sub.2, x and y are 1 or 2, and n is from 0 to 5.
