Polyacrylamide (PAM) is a linear polymer with the chemical formula (C3H5NO)n. It is a hard glassy solid at room temperature. Its products include glue, latex, white powder, translucent beads and flakes, etc. Good thermal stability. It can be dissolved in water in any proportion, and the aqueous solution is a uniform and transparent liquid. After long-term storage, the viscosity of the solution will decrease due to the slow degradation of the polymer, especially when the storage and transportation conditions are poor. [1] Polyacrylamide is used as a lubricant, suspending agent, clay stabilizer, oil displacing agent, water loss reducing agent and thickener in drilling, acidification, fracturing, water plugging, cementing and secondary and tertiary oil recovery. It is widely used in oilfield chemicals and is an extremely important oilfield chemical.
Medical materials
Polyacrylamide gel can be used as non-thrombin granulating agent, raw material for surgery, contact lenses, outer coating material of microcapsules, and used to manufacture high-quality hemostatic plugs, women's sanitary napkins and children's diapers, etc. Polyacrylamide with a particle size of several hundred microns to tens of microns can be used as chromatography packing (such as gel chromatography column packing), which can effectively separate globular proteins such as cytochromes. It can further desalt and concentrate proteins. The polyacrylamide resin undergoes Mannich reaction, introducing L-proline or L-hydroxyproline through the methylene bridge on the amide side chain, and then coordinates with copper ions to obtain a chiral ligand resin. Series of DL-amino acids for efficient separation. The chiral amino acids on the polyvinylamine resin obtained by Hofmann degradation are then complexed with copper ions. As the stationary phase of ligand exchange chromatography, a series of amino acids can be resolved, and the separation effect of aromatic amino acids is particularly good. Due to the structure of the skeleton, Strong hydrophilicity, greatly shortening the splitting time
