Ceric ion initiated synthesis of polyacrylamide grafted
Sigma-Aldrich offers abstracts and full-text articles by [Srijita Bharti, Sumit Mishra, Gautam Sen].
KMnO 4 and ceric salts-(organic) reducing agent systems in acid-aqueous medium were used for polymerization of vinyl monomers. These methods have also been used for the preparation of graft
Synthesis and characterization of polyacrylamide grafted
Ceric ion initiated solution polymerization was found to be satisfactory for the formation of copolymer. The effect of monomer concentration, initiator concentration, reaction time, and temperature, in terms of grafting efficiency (%GE) and percent of grafting (%PG), have been investigated.

Polyacrylamide grafted Agar: Synthesis and applications
2.2. Synthesis 2.2.1. Synthesis of polyacrylamide grafted agar by conventional method (using ceric ammonium nitrate (CAN) as the free radical initiator)[Ag-g-PAM(C)] Grafting reaction was carried out by ceric ion (Ce 4+) through direct oxidation. The details of the synthesis and the reaction conditions are as follows:
The synthesis and characterization of grafted hydroxypropyl guar gum by ceric ion induced initiation was studied by Nayak and Singh [14]. Grafting of acrylamide on to guar gum with the redox
Synthesis and characterization of grafted hydroxypropyl
A study was made of the ceric-ammonium-nitrate-initiated graft copolymerization of polyacrylamide onto hydroxypropyl guar gum by solution polymerization technique. Six grades of graft copolymers have been synthesized by varying catalyst and monomer concentrations. Synthesis and characterization of grafted hydroxypropyl guar gum by ceric ion

- What is nonionic polyacrylamide?
- Nonionic polyacrylamides Nonionic polyacrylamides represent the smallest group of acrylamide-based polymers, representing about 25% of the total polyacrylamide market. Nonionic polyacrylamide is somewhat misleading since in the manufacture of acrylamide, regardless of the route, some degree of hydrolysis of acrylamide occurs.
- Why is polyacrylamide not a polyamide?
- It can be viewed as polyethylene with amide substituents on alternating carbons. Unlike various nylons, polyacrylamide is not a polyamide because the amide groups are not in the polymer backbone. Owing to the presence of the amide (CONH 2) groups, alternating carbon atoms in the backbone are stereogenic (colloquially: chiral).
- What is an anionic polyacrylamide?
- Anionic polyacrylamides make up the largest portion of the polyacrylamide market. The polymers can be prepared over a wide range of anionic charges and molecular weights (1000 to > 20,000,000 molecular weight). The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid.
- What is a high molecular weight nonionic polyacrylamide?
- High-molecular-weight nonionic polyacrylamides are routinely used in the mineral processing industries as thickeners and flocculants , , . 34.2.5. Polyacrylamide product forms The product types for polyacrylamides are solutions, liquids (emulsion or dispersion), and dry powders.
