A novel polymeric flocculant based on polyacrylamide grafted
Novel functionalized polymeric flocculants based on polyacrylamide grafted carboxymethylstarch (CMS-g-PAM) have been successfully synthesized via conventional method (using ceric ammonium nitrate as free radical initiator, in an inert atmosphere) as well as by using microwave irradiation (‘microwave initiated’ synthesis).

The results of elemental analysis for inulin (In), polyacrylamide (PAM) and that of various grades of polyacrylamide grafted inulin (In-g-PAM) are given in Table 2. The data clearly shows that there is a considerable percentage of nitrogen in the graft copolymers, which can be attributed to the presence of grafted PAM chains.

Synthesis and characterizing a novel polymeric flocculant
The article highlights the development of a new generation of polymeric flocculant by grafting binary monomer mixture of acrylamide and acrylic acid onto a natural polymer—amylopectin [(AP-g-PAM)-g-PAA]. Primary graft copolymerization of acrylamide onto AP and binary graft copolymerization of acrylic acid onto AP-g-PAM was accomplished in 84 and 91 % grafting efficiency (% GE) using

Application of biomaterials to advance induced pluripotent
The hydrogel substrates bearing different functional groups, hydrophilicity, and matrix rigidity were synthesized via copolymerization of acrylamide (PAm) with synthetic heparin mimics [poly(sodium 4‐styrenesulfonate) (PSS)] or with monomers enriched with carboxylate groups using varied molar ratios.
