Ultra High Molecular Weight Polyacrylamide

Study on synthesis of ultra-high molecular weight polyacrylamide In recent years, the synthesis and application of ultra-high molecular weight polyacrylamide (HMW-PAAm) have received more and more attention and research. HMW-PAAm has good mechanical properties and can be used to prepare a variety of high-performance materials and devices, including hydrogels, nanofibers and multi-porous membranes. To prepare HMW-PAAm, it is necessary to synthesize it first. The purpose of this study is to explore the effective method of HMW-PAAm synthesis in order to find the effective process and the optimal conditions. First, according to the HMW-PAAm synthesis reaction during the experiment, the necessary raw materials were prepared, including polyvinyl alcohol (PEG), acrylic acid (AA), organic sodium tert-butylsulfonate (NaTBS) and methyl methacrylate (MMA), and each component was examined in detail before mixing these raw materials. The relevant raw materials usually need to be washed, filtrate an…
