Abstract
The influence of polymers as stabilizing additives for iron and manganese ions was investigated in an aqueous system. The polymers tested include: homo-polymers of acrylic acid, maleic acid, methacrylic acid, 2-acrylamido-2-methylpropane sulfonic acid; co-polymer of acrylic acid: vinyl acetate, acrylic acid: hydroxypropyl acrylate, acrylic acid: carbitol acrylate, acrylic acid: 2-acrylamido-2-methylpropane sulfonic acid; and ter-polymer of acrylic acid: methacrylic acid: acrylic acid: acrylic acid: 2-acrylamido-2-methylpropane sulfonic acid: sulfonated styrene, acrylic acid: 2-acrylamido: t-butylacrylamide. It was found that polymer architecture i. e., monomer type, monomer charge, molecular weight, and polymerization solvent, strongly influences the performance of polymer as iron and manganese ions stabilizing additives. The stabilization data reveal the following order in terms of decreasing polymer performance: ter-polymer > co-polymer > homo-polymer.
Kurzfassung
Der Einfluss von Polymeren als Stabilisierungsadditiv für Eisen- und Manganionen wurde in einem wässrigen System untersucht. Die getesteten Polymere waren: Homopolymere der Acrylsäure, Maleinsäure, Methacrylsäure, 2-Acrylamido-2-methylpropansulfonsäure; Copolymere von Acrylsäure: Vinylacetat, Acrylsäure: Hydroxypropylacrylat, Acrylsäure: Carbitolacrylat, Acrylsäure: 2-Acrylamido-2-methylpropansulfonsäure; und Terpolymere von Acrylsäure: Methacrylsäure: Acrylsäure: Acrylsäure: 2-Acrylamido-2-methylpropansulfonsäure: sulfoniertes Styrol, Acrylsäure: 2-Acrylamido: t-butylacrylamid. Es wurde gefunden, daß die Polymerarchitektur, d.h. Monomertyp, Monomerladung, Molekulargewicht und Polymerisationslösungsmittel die Leistung des Polymers als Stabilisierungsadditiv für Eisen- und Manganionen stark beeinflusst. Die Stabilisierungsdaten zeigen die folgende Reihenfolge bezüglich abnehmender Polymerleistung: Terpolymer > Copolymer > Homopolymer.
