physical and chemical characterisation of acrylamide-based

the 1 h nmr spectrum of polyacrylamide polymers showed characteristic proton peaks at 3.9 and 4.30,5.50, 7 and 7.90 ppm which represent the alkene group (=ch) in the polymer. the peaks at 3.9 ppm correspond to protons of the carbon–carbon double bond.

cheap nonionic polyacrylamide (pam) in nigeria,polymer adsorption can occur through hydrogen bonding (polyacrylamide on silica silanol groups), electrostatic interaction (cationic polymers on negatively charged sludge), hydrophobic interaction (poly(vinyl alcohol) on silver iodide), and ion bridging (anionic polyacrylamide on negatively charged clays with the help of divalent calcium ion

research on a new cationic polyacrylamide (cpam) with high quality,the cationic monomers on these microblock segments can be polymerized to form a cpamd with a new cationic microblock structure. in addition, microwave has mechanical effects such as oscillation, emulsification, and diffusion, which can accelerate the heat and mass transfer process of the reaction system, thus accelerating the reaction rate (wiesbrock et al. 2004; hoogenboom and schubert 2007

amide additives improve rdc measurements in polyacrylamide

the interactions between polyacrylamide and pdz3 are lessened by amide-containing compounds. indeed, the rdc data collected in pbs yielded a poor fit to the crystal structure of pdz3 as indicated by a high q value (q 0.66, fig. s3). addition of either an asn gln mixture or propionamide improved the fitting quality to q 0.49 (fig. s3).

the new approach to the preparation of polyacrylamide-based

the new initiator of the polymerization of acrylamide, leading to the formation of crosslinked polyacrylamide, was discovered. the structure of the synthesized polyacrylamide was characterized by xrd, 1h nmr, and 13c nmr spectroscopy. it was shown that 1,3-dimethylimidazolium (phosphonooxy-)oligosulphanide is able to initiate radical polymerization under drying aqueous solutions of acrylamide
