Because the length of polymer can be determined, the properties of various poloxamers are slightly different. Usually, this kind of * * * polymer uses the letter "P" (poloxamer) plus three digits as the common name. The first two digits are the approximate molecular weight of polyoxypropylene, and the last digit is the percentage of polyoxyethylene (for example, P407 indicates that polyoxypropylene with a molecular weight of 4000g/mol contains 70% polonium composed of polyoxyethylene). For its commercial name Planik, its identification code is a letter, indicating its physical form at room temperature (L: liquid, P: paste, F: flake (solid)), with two or three numbers, the first number (and the first two numbers in the case of three numbers) multiplied by 300 indicates the approximate molecular mass of hydrophobic substances, and the last number x 10.
[Edit] Application
Because of its amphoteric molecular structure, the surface activity of polymer makes it suitable for industrial application. In addition, it can be used to increase the water solubility of hydrophobic oily substances or increase the miscibility of different hydrophobic substances. Therefore, this polymer is often used in industrial products, cosmetics and medicines. It is also used to evaluate many drug delivery applications and show sensitivity to drug-resistant cancers in chemotherapy.
In the application of biological process, Planck is also used in cell culture medium, because it can reduce the extra shear of cells in the reactor and has a buffering effect on cells.
