Abstract
Cationic polyacrylamide (CPAM) was prepared in aqueous solution by free radical polymerization of methacryloyloxy ethyl trimethylammonium chloride (DMC) and acrylamide (AM). A redox initiator system was used. The structure of CPAM was characterized by IR and 1H NMR. The intrinsic viscosity and cationicity of CPAM were measured by an Ubbelohde viscometer and titration experiments, respectively. It was found that at the same concentration, the intrinsic viscosity decreases as the cationicity increases. The antistatic properties of CPAM on polyester fabric, the combability of hair, the flocculation on diatomaceous earth in a simulated sewage system and the thickening effect in solution were investigated. The results show that the higher the concentration, cationicity and intrinsic viscosity of CPAM, the better the thickening effect and the better the combability, the antistatic and flocculation properties. Therefore, the production of CPAM with high intrinsic viscosity and cationicity is important for an enhanced application performance.
Kurzfassung
Kationisches Polyacrylamid (CPAM) wurde durch radikalische Polymerisation von Methacryloyloxyethyltrimethylammoniumchlorid (DMC) und Acrylamid (AM) in wässriger Lösung hergestellt. Es wurde ein Redoxinitiatorsystem verwendet. Die Struktur von CPAM wurde durch IR-Spektroskopie und 1H-NMR ermittelt. Die Grenzviskosität und Kationizität von CPAM wurden mittels eines Ubbelohde-Viskosimeters bzw. mit Hilfe von Titrationsexperimenten gemessen. Es wurde gefunden, dass bei gleicher Konzentration die Grenzviskosität abnimmt, wenn die Kationizität zunimmt. Die antistatischen Eigenschaften von CPAM auf Polyestergewebe, die Kämmbarkeit von Haaren, die Flockung auf Kieselgur in einem simulierten Abwassersystem und die Verdickungswirkung in Lösung wurden untersucht. Die Ergebnisse zeigen, dass die Verdickungswirkung umso besser ist, je höher die Konzentration, die Kationizität und die Grenzviskosität von CPAM ist und je besser die Antistatik-, Kämm- und Flockungseigenschaften sind. Daher ist die Herstellung von CPAM mit hoher Grenzviskosität und Kationizität für eine verbesserte Anwendungsleistung wichtig.
