Synthesis of linear cationic polyacrylamide (CPA) with chlorinated chain ends The CPA was prepared by free radical polymerization using AM and DMC. Specially, AM and DMC were firstly added into a 150 mL three-necked flask according to the recipe in Table 1 , then a certain amount of CS was added as the chain transfer agent.

Synthesis and Characterization of Novel Smart Flocculant
In addition, using of these graft copolymers as flocculants has been studied and characterized in detail. 6-13 Furthermore, cationic polyelectrolyte flocculants have been prepared by modification of polyacrylamide or the copolymerization of acrylamide with comonomers having cationic electrolyte groups. 14-16 Polyethyleneimine has been prepared
Fig. 1 Synthesis of diblock copolymer particles with the general formula ([1 − n]PGMA x + n PAMA y)–PHPMA z by RAFT aqueous dispersion polymerisation using a binary mixed macro-CTA approach. Optimisation of parameters n, x, y, and z result in the formation of spheres, worms or vesicles that are cationic at low pH, and both colloidally stable and reactive at high pH.

Full Article. Synthesis of Cationic Xylan Derivatives and Application as Strengthening Agents in Papermaking. Fangong Kong, a * Yanquan Guo, a,b † Zhongming Liu, a Shoujuan Wang, a * and Lucian A. Lucia a,c Cationic xylan derivatives were prepared by etherification using 3-chloro-2-hydroxypropyltrimethylammonium chloride as the cationic reagent under an alkaline condition.
Wang and coworkers 37 articulated that an increase in the charge density of cationic xylan from 1.8 to 2.4 meq/g enhanced the adsorption of cationic polymer from 3.1 to 4.6 mg/g onto kaolin
Synthesis, properties and performance of organic polymers
In this review, we have described the synthesis techniques and flocculation efficiency associated with several non-ionic (1–26, cationic (27–59), anionic (60–72) and amphoteric (73–82) polymers, and a summary of each type of polymeric flocculant is presented in Tables 1–4, respectively. The development of synthetically-modified
As shown in Fig. S3, the equilibrium absorption capacities are decreased from 1008.65 to 298.64 mg g −1 for NR, 393.25 to 168.82 mg g −1 for MB, 810.67 to 251.30 mg g −1 for MV and 553.37 to
