Polyvinyl alcohol (PVA) is a water-soluble polymer material widely used in the preparation of hemostatic fibers, artificial skin, plasma substitutes, etc. It can also be used as a drug sustained-release carrier material to prepare targeted microspheres. Animal experiments have shown that it is completely harmless and has good biocompatibility. It can be slowly degraded in the body, so it is widely used as a drug carrier. Polyvinyl alcohol microspheres with a particle size of less than 10 microns release drugs into the human body to achieve the purpose of treatment and immunity. For example, PVA microspheres made of erythropoietin, interferon, and cholera toxin B subunit can be absorbed orally. Through dispersion polymerization, polyvinyl alcohol microspheres with a size of 1-10μm can be prepared, and they can also be further chemically converted into various types of functionalized microspheres according to the different requirements of the application field.   Polyvinyl alcohol foam embolic microspheres are medical substances used for embolization of blood vessels. They are mainly composed of polyvinyl alcohol and/or polyglycolide and are specially treated to enable them to swell and embolize blood vessels. Such microparticles are often used in intravascular surgery to prevent blood from flowing into and contaminating the surgical area. In addition, they can also be used to treat ischemic stroke and other vascular diseases.   Features of polyvinyl alcohol foam embolic microspheres include: it can swell upon contact with blood and quickly solidify, thereby effectively embolizing blood vessels. The microspheres are degradable and will be absorbed by the body after a period of time, which helps reduce the risk of complications.

PVA is the abbreviation of polyvinyl alcohol, which is a water-soluble polymer material with high hydrophilicity. PVA is often used in the manufacture of cosmetics, paper, glue, coatings, food packaging and other fields. PVA has good solubility. The dissolution method of PVA varies depending on the application field and demand, and each method has its own unique advantages and disadvantages. Choosing a suitable dissolution method can improve the solubility and stability of PVA, making it more widely used in different fields.   1. Temperature rise dissolution method The temperature rise dissolution method is one of the most commonly used methods for dissolving PVA. Add PVA powder to an appropriate amount of water, then stir evenly and heat to an appropriate temperature to completely dissolve the PVA. Normally, the dissolution temperature of PVA is between 60 and 95 ℃. The dissolution temperature of PVA is related to its degree of polymerization and acetate content. The higher the degree of polymerization, the more acetate content, and the higher the dissolution temperature. The solubility and dissolution rate of PVA can be controlled by changing the temperature and time.   2. Dissolution by auxiliary agent In addition to directly adding PVA to water for dissolution, the solubility and stability of PVA can also be improved by adding auxiliary agents. Common auxiliary agents include acetone, methanol, ethanol, phenol, etc. These auxiliary agents can form hydrogen bonds or other interaction forces with PVA, thereby improving solubility. The addition of auxiliary agents can also shorten the dissolution time of PVA.   3. Slow cooling and dissolution The slow cooling method is a special PVA dissolution method, which is suitable for the preparation of polymers, micro-nano particles, films, fibers and other materials. The basic principle of the slow cooling method is to add PVA powder into water, heat it to dissolve it, and then slowly cool it down to make the PVA molecules self-assemble to form nanoparticles, nanofibers or films. The slow cooling rate has an important influence on the self-assembly process of PVA. Generally speaking, the slower the slow cooling rate, the more complete the structure of the PVA self-assembly. The slow cooling method is mainly suitable for the preparation of micro-nano materials.   4. Gas phase dissolution The gas phase method is a relatively new PVA dissolution method. In this method, the PVA solid enters the atmosphere through the dissolution hopper. By controlling the temperature, pressure and atmosphere composition, the PVA solid is directly evaporated into gaseous molecules, and then transported to other equipment through a transmission pipe for reaction or solidification to form a corresponding block. Unlike the traditional dissolution method, the gas phase method can prevent the PVA molecules from being affected by water decomposition, thereby maintaining the integrity and quality of the material.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.
