Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH 2 CHCONH 2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N,N '-methylenebisacrylamide.In the cross-linked form, the possibility of the monomer being present is reduced even further.

2.2.2. Purification of the graft copolymer by solvent extraction method. Any occluded polyacrylamide (PAM) formed by competing homopolymer formation reaction was removed from the graft copolymer synthesized as above, by solvent extraction using a formamide–acetic acid mixture (1:1 by volume) (Sen & Pal, 2009a).2.3.

Anionic polyacrylamide APAM [ APAM Properties] According to different uses, anionic polyacrylamide is sorted into two kinds of manufacturing technique. 1. Homopolymerization ( hydrolysis and posthydrolysis of Non-ionic polyacrylamide). 2. Copolymerization ( acrylamide, acrylic acid or sodium acrylate ).
The above is the search results for Chinese Polyacrylamide, click for more recommended manufacturers & suppliers listings such as water treatment, anionic polyacrylamide, pam. The global chemicals industry faces economic and environmental pressures, that's why many of our suppliers like Polyacrylamide factory are always innovating to provide
water for 20 min, and then the pH of the reaction solution was adjusted to 1.5 using sulphuric acid. This treatment precipitated the SL-AM copolymer. The suspension was centrifuged at 3000 rpm for 10 min in order to collect the precipitated copolymer and to remove the homopolymer (polyacrylamide; PAM) and unreacted acrylamide monomer.

The hydrolysis of polyamides has been studied in buffered acid solution at 110°C. at an amide concentration of 0.05 M .In the case of polyacrylamide, the reaction was carried out in acetate buffer at different values of the ratio r (acetic acid/sodium acetate). The initial velocity is low and is proportional to the concentration of acetic acid; the rate constant is equal to 2.6 × 10 −6
The hydrated PAM is a softthat is used inelectrophoresis and as a super water-absorbing polymer (SAP's). Even though these polymers are called polyacrylamide, they are often copolymers of acrylamide and one or more other monomers. The most important co-monomer is acrylic acid or sodiumacrylate.
PAM is currently used as a soil conditioner on ~800,000 ha 33 of irrigation land in the U.S., corresponding to 900–18,000 tons of PAM per year. PAM binds with soil particles through
The graft copolymerization reaction was carried out for various concentration of substrate. The concentration of the AP was varied from 0.5 to 3.5 g for both the graft copolymerization reaction at constant monomer concentrations AM (0.107 mol/L) and DMA (0.107 mol/L), initiator (CAN) concentration (4.8 × 10 −4 mol/L), reaction time (5 h) and reaction temperature (35 °C).
Polyacrylamide (PAM) copolymers used, unless noted otherwise, was a dry granular material having an approximate molecular weight of 12-15 Mg/mole, with an 18% negative charge density, manufactured by CYTEC Industries of Wayne, NJ. It is marketed in the US by American Cyanamid Company under the trade name Superfloc 836A.
