Abstract

A method for intentionally coating a polymerization reaction vessel capable of substantially eliminating the formation of polymers on the internal surface of said container characterized by applying to said surface of the coating consisting of a linear or branched chain polyaromatic amine with a higher molecular weight at about 250 dissolved in an organic solvent, said polyaromatic amine presenting the structure **(See formula)** in which A, B and C are **(See formula)** where R5 is (see formula) or a straight or branched chain alkylene or alkylidene group containing 1 to 5 carbon atoms, or **(See formula)** and in which A, B, and C can be the same or different, and each repeating unit can be the same or different; R1 and R2 are -H, -OH, -NH2 or **(See formula)** and they can be the same or different; R3 is -H, halogen or an alkyl group containing 1 to 8 carbon atoms and can be the same or different; R4 is -H, -OH, -NH2 or an alkyl group containing 1 to 8 carbon atoms and can be the same or different, and when more than two groups R3 and R4 are present, at least two are -NH2 or -OH or one of each; x is an integer from 1 to 20; and y is an integer from 0 to 20; and **(See formula)** in which A and B have the same meaning as in (A); R1, R3, R4 and R5 have the same meaning as in (A); R2 is -H, -OH or x is an integer from 1 to 4; and y is an integer from 1 to 15.
