Stabilizer-Free Aqueous Two-Phase Copolymerization
A series of cationic polyacrylamides (CPAMs) with different charge densities have been prepared via the stabilizer-free two-phase copolymerization of acrylamide (AM) and 2-methylacryloylxyethyl tri...
A novel method for one-step preparation of antifouling ultrafiltration membranes via a non-solvent induced phase separation (NIPS) technique is proposed. It involves using aqueous 0.05–0.3 wt.% solutions of cationic polyelectrolyte based on a copolymer of acrylamide and 2-acryloxyethyltrimethylammonium chloride (Praestol 859) as a coagulant in NIPS.
Preparation of polyacrylamide based microgels with
The aqueous phase (∼9 mL total) contained water, acrylamide, bis-acrylamide, allylamine (only for cationic hydrogels) and AMPS (only for anionic) hydrogels, and APS. The organic phase consisted of 9 mL cyclohexane with dissolution of 900 μL of Span 80 as surfactant to stabilize the emulsion droplets.

Synthesis of cationic polymer-grafted cellulose by aqueous
The pulp and paper industry already extensively uses cationic polymers to increase the mechanical properties of cellulose fibers, in part due to the negative charge carried by fibers in aqueous media. Use of polymers such as cationic polyacrylamide or cationic starch which adsorb to the fibers surface is already well established and understood .

In the current work, we have reported a cationic surfactant-modified Ethiopian kaolin for improved adsorption of Cr(VI) from aqueous solution. The raw kaolin was modified by treating with CTAB to enhance the adsorption properties. The crystal structure and vibrational analysis of CTAB–kaolin were investigated by Fourier transform infrared spectroscopy (FTIR) and powder X-ray diffraction (p
