| abstract | (57) [Summary] [Object] To provide a polymer-based antioxidant capable of protecting an oxidizable polymer from the destructive action of oxygen for a long time. [Structure] Diphenylamine and an acid-activated clay catalyst are added to toluene, stirred rapidly, heated and refluxed to remove water. Next, the toluene was distilled to raise the reflux temperature to 130 ° C., and a boiling toluene solution of 1,4-di- (α-hydroxyisopropyl) benzene was added thereto, Maintain at reflux temperature of 2 ° C. for 30 minutes. Toluene is removed from the solution, refluxed at 130 ° C. for 30 minutes, then toluene is added, filtered at 112 ° C., and the filtrate is rotary evaporated. Removal of excess diphenylamine from the light pink evaporation residue under vacuum gives the pale yellow desired resin. |
