  • Procedure for the anti-scaler production for coating the polymerizing reactor and respective resultant product
    Patent number: 6080332
    Abstract: The invention comprises a novel process for producing an anti-scaler coating for monomer polymerization reactors comprising mixing hydroxymethansulphincal acid with 1-naphthol. The invention also comprises an anti-scaling product obtained by this novel process.
    Type: Grant
    Filed: March 6, 1998
    Date of Patent: June 27, 2000
    Assignee: C.I.R.S. S.p.A.
    Inventor: Mario Sattin
  • Anti-scaling agent for coating of polymerization reactors
    Patent number: 6069199
    Abstract: The object of the invention is to provide a liquid anti-scaler for coating polymerizing reactors obtained by a condensation reaction of naphthol with an aldehydic cross-linking product, wherein the cross-linking product is the reaction product of hydrosulfite and formaldehyde. It contains hydrosulfite and/or radical bisulfites and/or bisulfite. The condensate is made in such a way that in the absence of oxygen, it is in the form of liquid of clear transparent color.
    Type: Grant
