Synthesis of Star Cationic Polyacrylamide and its
A new kind of star cationic polyacrylamide (S-CPAM) based on AM and DMC was synthesized via reversible addition-fragmentation chain transfer (RAFT) polymerization. The structure of the resulting product was characterized by FT-IR. S-CPAM was used as retention aid for papermaking and the influence of the application conditions such as dosage of S-CPAM, shearing, action time and pH value on the
In the flocculation treatment of oilfield sewage, cationic polyacrylamide (CPAM), which was synthesized by the copolymerization of dimethyldiallylammonium chloride (DMDAAC), acrylamide(AM), and acrylic acid(AA), will react with the residue of oil displacement agent, causing the quick crimp of its linear-molecular-structure chain and deteriorating the flocculating effects.

Synthesis, characterization and application of novel
Polyacrylamide and cationic polymer based flocculants used in wastewater and industrial effluent treatment are highly efficient at low doses. But they are fragile and expensive. On the other hand, polysaccharides are cheap, biodegradable, shear stable but less effective as flocculants ( Singh et al., 2003 , Singh et al., 2009 , Krishnamoorthi

Synthesis, Characterization, and Flocculation Properties
2.3. Synthesis. The branched cationic polyacrylamide was synthesized using AM and DAC in an aqueous solution. The AM and distilled water were added to a 250 mL three-necked flask equipped with a stirrer and a thermometer. The solution was bubbled with nitrogen for 30 minutes to remove oxygen.

Defensins Knowledgebase - Literature
Human-defensins (h beta D1 and h beta D2) were also included in the study. Two types of cellular fractions from Caco-2 cells were tested: (i) cytosolic fractions, obtained by sonication of cultured human enterocytes and (ii) cationic fraction, obtained by batch extraction of the cytosolic fraction with a weak cation exchange resin.
