ABSTRACT:
A monomer having an ethylenic double bond is polymerized in a polymerization vessel provided on its inner wall surfaces with a coating of a polymer scale preventive agent which comprises a condensation product of an aromatic amine compound with an aromatic hydroxyl compound condensate. This process makes it possible to prevent effectively the deposition of polymer scale and to produce a polymer which shows few fish eyes and good whiteness when formed into sheets or the like.
