  • Polyacrylamide Polymer - an overview | ScienceDirect

    An electric field is applied to the gel and causes the proteins to migrate towards the other end of the strip. Individual proteins migrate until they reach their isoelectric point. In the second dimension, sodium dodecyl sulfate (SDS) polyacrylamide polymer networked gels are used. In this separation mechanism, the proteins are separated based upon size.

    2016-5-22 · Abstract: The polymerization was carried out under the different concentrations of acrylamide and crosslinker in an aqueous solution of NO2 gas as initiator at 50 ºC. The resulting polyacrylamide was saponified with NaOH solution. The hydrolysed polymers show high degree of water swelling (> 500) than that of unhydrolysed polymers (< 100). Swell ability of the gel decreases with the increasing concentration of N, N’- methylene bisacrylamide – a crosslinker which enhances the degree of crosslinking in the polymer chains. The increased crosslinking restricts the expansion of polymer network which causes the lowering of the water absorbency. It was observed that polymer hydration increased with the molar mass of polyacrylamide. The swell ability of polyacrylamide …
