पॉलीक्रिलिक acidसिड - व्हिस्टीक


पॉलीक्रिलिक acidसिड म्हणजे काय?


पॉलीप्रोपायलीन (पीएए; व्यापार नावकार्बोमर) is a synthetic high molecular weight propylene polymer. IUPAC is named poly(1-carboxyethylene). They can be homopolymers of acrylics or cross-linked with acrylics of pentaerythritol, acrylics of sucrose, or acrylics. In aqueous solutions at neutral pH, पीएएs are anionic polymers, meaning that many of the side chains of पीएएs lose their protons and thus gain loading. This makes पीएएs polyelectrolytes with the ability to absorb and retain water, which can swell to many times their original volume.


Dry पीएएs are sold as white, fluffy powders and are commonly used as gels in cosmetics and personal care products. Their cosmetics role is to suspend solids in liquids, prevent emulsions from separating, and control the flow of cosmetics. The carbomer codes (910, 934, 940, 941, and 934P) indicate the molecular weight and specific composition of the polymer. In numerous applications, पीएए is used in alkali metal or ammonium salts, such as sodium polyacrylate. The positively charged sodium ion is bound to the polyacrylate in dry powder form, but in an aqueous solution, the sodium ion disintegrates. This causes the gel to swell rather than organizing the polymer chains, which can absorb large amounts of water.


पॉलीप्रोपायलीन is a weakly anionic polyelectrolyte, and its degree of ionization depends on the pH of the solution. In the non-ionized form at low pH, पीएए can bind to various non-ionic polymers (e.g., polyethylene oxide, poly-N-vinyl pyridone, polyacrylamide, and some cellulose ethers) to form hydrogen-bonded interpolymer complexes. In aqueous solutions, पीएए can also form polymers with oppositely charged polymers (e.g., chitosan), surfactants, and drug molecules (e.g., streptomycin).


काय आहेपॉलीक्रिलिक acidसिडसाठी वापरतात?


पॉलीक्रिलिक acidसिड and its derivatives are used in disposable diapers, ion exchange resins, and adhesive detergents. Detergents are usually copolymers of acrylic acid and can be used as zeolites and phosphates in detergent formulations. It is also popular as a thickening, dispersing, suspending, and emulsifying agent in pharmaceuticals, cosmetics, and coatings. Cross-linked polypropylene is also used in the processing of household products such as floor cleaners. Acrylic acid is also a major component of superabsorbent polymers (SAPs), and cross-linked polyacrylates can absorb and retain more than 100 times their own weight in liquid.पीएए can deactivate the bactericide chlorhexidine gluconate.After neutralization, पॉलीक्रिलिक acidसिड gels are suitable for biocompatible matrices that receive medical applications, such as skincare and dermatological treatment product gels.पीएए films can be deposited on orthopedic implants to avoid corrosion. Cross-linked hydrogels of AA and gelatin are also used as medical gels with high bond strength. Recent studies have aimed to clarify the conformational changes of polymeric gels upon neutralization, light exposure, and embedding of gold nanoparticles to develop polymeric matrices that can control the rate of delivery of active substances. The FDA has authorized the use of SAPs in packaging for indirect food contact.

How do you dissolve पॉलीक्रिलिक acidसिड?


पीएए polymers contain a large number of carboxyl groups (-COOH). As a result, the hydrogen bonds between each chain are powerful and dissolved in organic solvents such as DMSO and NMP. First, we must consider the forces that break the hydrogen bonds of the पीएए chains. Primary solvents (H2O, ethanol, etc.) are good sources of protons (H+), so these are attached to the carboxyl groups. Therefore, all carboxylic acid groups that acquire protons positively charge, indicating that hydrogen bond breakage drives the chain. Therefore, solvents for solubilizing पीएए polymers are suitable for using native proton solvents, which can be searched in Google.
