ABSTRACT:
A process to inhibit scale adhesion to the interior of a polymerization vessel using a two part coating composition. The coating is a hydroxyanthraquinone compound used in conjunction with a water soluble salt of chitosan, applied as a solution and dried on the vessel interior. Advantages of the coating are its effective scale prevention, unaltered color of the polymer product and low toxicity.
