Synonym: Poly(NIPAM-co-MAA-co-ODA), Polyacrylamide, functionalized polyNIPAM, functionalized polyacrylamide, polyNIPAM Linear Formula: (C 6 H 11 NO) m (C 4 H 6 O 2 ) n (C 21 H 40 O 2 ) p 724475
The radiation‐induced polymerization of acrylamide was studied to prepare a high molecular weight and highly effective polyacrylamide flocculant. Among various solvents, mixtures of water– tert ‐butyl alcohol and water–acetone were found to be suitable for the synthesis of the high molecular weight polyacrylamide.

Use according to one of claims 1 to 10, characterized in that the water-in-water polymer dispersion as a dispersant at least one Mono- and / or copolymer of acrylic acid and acrylic acid derivatives and / or Maleic acid and maleic acid derivatives, preferably from an alkali salt Acrylic acid, a polyol, preferably a polyalkylene glycol, polyvinyl alcohol, Polyvinyl pyrrolidone, polyimine
Important nonionic water-soluble polymer. High MW polymer is used primarily as a flocculant. Tg of high MW (>100,000) polymers = 165º. Unit weights are weights in solution (e.g. 10% soln. in water is 25g polymer in 19901-250)
Polyacrylamide Market Size, Share & Growth | Industry
Polyacrylamide (PAM) is a synthetic, potassium based long-chain polymer. It has a high-molecular weight and is a kind of water-soluble polymer, that is produced through polymerization of acrylamide. The global polyacrylamide market will grow at an impressive rate owing to its increasing use mainly in petroleum and wastewater sector.
Polymer molecular weight standards were prepared by techniques which yield narrow molecular weight distribution and when this is not possible by fractionation of polymers of broader molecular weight distribution. We have listed standards of a range of molecular weights for widely studied polymers. Germany +(49) 6201 845 20 0 +(49) 6201 845

Choose the polyacrylamide percentage and type of well for your application based upon the expected molecular weight of your protein of interest and the volume of your sample. Resolve large molecules with low percentage gels and small molecules with high percentage gels.
The effect of KCl concentration on adsorption of HMPAM on alumina surfaces was shown in Fig. 2.As shown in Fig. 2(a), Δf decreased from 0 to -13.1 Hz and ΔD increased to 2.0 × 10 −6 in 10 mM KCl, indicating a dissipative layer of HMPAM was adsorbed on alumina surface. In Fig. 2(b), Δf decreased to -21.8 Hz with the increase of ΔD to 6.0 × 10 −6 in 100 mM KCl, which means that the
