POLYMER SCALE DEPOSITION INHIBITOR, POLYMERIZER PROTECTED AGAINST POLYMER SCALE DEPOSITION, AND PRODUCTION OF POLYMER USING THE SAME

摘要

PURPOSE: To effectively prevent a polymerizer from suffering polymer scale deposition not only on a polymerizer's part which is in contact with the liquid phase but also on a polymericer's part around the interface between the gas and liquid phases, and to produce a polymer product which gives a molding having extremely diminished fish eyes, a high degree of whiteness, and improved initial colorability. ;CONSTITUTION: The title inhibitor, which is used in the polymerization of an ethylenic monomer, comprises a condensate obtained by adding an aromatic hydroxy compound to a reaction system where an aromatic amine is undergoing condensation. The polymerization for producing a polymer is conducted in a polymerizer having, on its inner wall, a coating film formed from this inhibitor.;COPYRIGHT: (C)1993,JPO&Japio
