Abstract
PURPOSE: To prevent polymer scale deposites on the interior of a polymerizer, by coating the interior with the reaction product between a phenol compound and an aromatic aldehyde.
CONSTITUTION: (A) One mole of pyrogallol or hydroxyhydroquinone alone or a phenol compound containing it is reacted with (B) 0.1W1mole of an aromatic aldehyde in an aqueous or alcoholic medium under acidic conditions at 60W120°C to give the objective substance having a molecular weight of 308W2,000. In the case of other phenol compounds, e.g. phenol or p-bromo-phenol, the amount is 50mole% or less based on the pyrogallol or hydroxy-hydroquinone. preferably, an unsubstituted benzaldehyde is used as (B).
