Physicochemical properties: white crystalline powder, tasteless, very little moisture absorption. In case of high temperature or strong light, it is self crosslinked and slightly soluble in water and ethanol. A mixture of acetone dissolved in water and water. 0.31g/ml is soluble in water at 20 ℃, and the aqueous solution can form acrylic acid and ammonia due to hydrolysis. Melting point > 300 ℃. Moderate toxicity, LD50 (rat, oral) 390mg / kg. It's irritating. This product has certain toxicity due to its substituent acrylamide. It can slightly irritate eyes, skin and mucous membrane. Avoid direct contact with human body for a long time. If it is touched by mistake, clean it with clean water
Purpose: biochemical research. Separation of biopolymer compounds (protein, polypeptide and nucleic acid). Polyacrylamide gel technology and clinical examination. It can be copolymerized with acrylamide to make oilfield fracturing fluid, and it can be copolymerized with some monomer to make insoluble resin, which can be used as water shutoff grouting material. It can also be used as a crosslinking agent for preparing polyacrylamide gel. It is used in the production of printing and dyeing auxiliaries, napkins, health diapers and other super absorbent resins used in industry. Clinical test is an important material for separating amino acids. In underground buildings, the insoluble gel formed by injecting AAM and MBA into the soil layer strengthens the soil layer to prevent seepage. Adding concrete can shorten the curing time of concrete and improve the water resistance. In addition, MBA is also widely used in electronics, papermaking, printing plate making, synthetic resin modification, coatings, adhesives and so on
