    How do I synthesise ultra high molecular weight

    How do I synthesise ultra high molecular weight Polyacrylamide? Physicist asking dumb questions alert: I want to synthesise polyacrylamide with a molecular weight ~ millions of Da. I want to do this so that I can add a small quantity of other monomers into the backbone. I've made a PAM gel before using TEMED as an initiator and bis-acrylamide as the crosslinker. 1. Do I simply do the same

    SYNTHESIS AND CHARACTERIZATION OF

    Stable water-dispersible nanohydrogels of cross-linked polyacrylamide (PAAm) were obtained by batch (BP) and semicontinuous (SP) processes through inverse microemulsion polymerization using N,N'-methylenebisacrylamide (NMBAM) as cross-linking agent and bis(2-ethylhexyl) sulfosuccinate sodium salt (AOT) as surfactant.

    The effect of polyacrylamide charge density and molecular

    Several studies have shown that high molecular weight anionic polymers (e.g. polyacrylamide) are commonly used in the settling of negatively charged kaolinite,,,. In this case, the polymer bridging mechanism is of primary importance, whereas charge neutralization will be of secondary or little importance . The use of high molecular weight
