Process of producing polymer using a polymer scale deposition preventive agent |
摘要 |
A process is provided for preparing a polymer from an ethylenically unsaturated monomer, wherein the process provides reduced polymer scale deposition both in the liquid-phase region of the polymer vessel and on areas around the interface between the gas phase and the liquid phase, the process involving the use of a polymer vessel having a coating on at least its inner surfaces of a polymer scale preventive film prepared from a polymer scale preventive agent of a salt, either alkali metal, ammonium or both, of a sulfonation product of a condensate prepared from (A) an aromatic amine compound and (B) an aldehyde.
