| titleOfInvention | Scale deposit inhibitor, process for its production, polymerizer whose inside wall is covered with the inhibitor, and process for production of vinylic polymers by the use of the polymerizer |
| abstract | A scale adhesion preventing agent for use in anpolymerization reactor, consisting essentially of ancondensate of a phenol represented by the following formulan(1), a 1-naphthol and an aldehyde, which is soluble in annalkaline aqueous solution:n nwherein R 1 and R 2 are the same or different and each a hydroxylngroup, alkyl group having 1 to 8 carbon atoms, halogen atom,nhydrogen atom, alkoxycarbonyl group whose alkyl moiety hasn1 to 8 carbon atoms or phenyl group, with the proviso thatna hydrogen atom is existent at at least two of ortho-positionsnand para-positions with respect to the hydroxyl group. n When a vinyl-based monomer is to be polymerized usingna polymerization reactor having a film of this scale adhesionnpreventing agent on the inner wall, the vinyl-based polymerncan be produced by preventing the adhesion of a scale. |
