    2020-2-18 · Finally, three starch-based and two cellulose-based polymers were selected for flocculation and filtration tests. In shearless dewatering conditions, the retention and dewatering properties of the starch-based polymers were similar to those of commercial polyacrylamide-based polymers. The flow studies in higher shear

    Later, it has been found in our laboratory that amylopectin-g-polyacrylamide (AP-g-PAM) exhibits better flocculation properties in comparison with starch-g-polyacrylamide (St-g-PAM) and amylose-gpolyacrylamide (AM-g-PAM), which is due to the high molecular weight and highly branched nature of amylopectin [13,14].

  • Application of composite degradable modified starch

    2020-9-23 · The appearance of the new peaks in the spectrum of the CDF indicates that PAM was successfully grafted onto starch. As a contrast, the characteristic absorption peak at 2,930.35 cm −1 represents methylene anti-telescopic vibration, which was the characteristic absorption peak of PAM ( Chang et al. 2008 ).

  • Photoinitiated Polymerization of Cationic Acrylamide

    In this paper, synthesis of the cationic polyacrylamide P(AM-DAC) was investigated using a novel initiation system, photoirradiation. 2,2′-Azobis(2-amidinopropane) dihydrochloride (V-50) was introduced into the system as the photoinitiator for the polymerization of acrylamide with DAC as the cationic monomer in aqueous solutions.
