ABSTRACT:
To reduce fouling on reactor surfaces, the surfaces are coated with a protective film of polymeric material of surface energy of less than 15 dynes/cm. The preferred coating materials are polymers of one or more monomer chosen from the 2-(N-alkylperfluorosulphonamido)) alkyl (meth)acrylates or the fluorochemical polymer known as Fluorad (Registered Trade Mark of the 3M company) FC-721.
