摘要: Poly(ortho-methylphenol) is obtainable at high purities and yields using industrial processes by causing a secondary amine and formaldehyde to react with a polyphenol (first step), and then breaking down the aminomethyl group of the obtained poly(ortho-aminomethyl)phenol by means of hydrogenolysis in the presence of a hydrogenation catalyst (second step).
