WebOct 24, 2013 · Carbomers are readily dispersible in water and in mixtures of polar organic solvents with water, such as 70% w/w ethanol-water solution. When initially prepared, … In a water solution at neutral pH, PAA is an anionic polymer, i.e., many of the side chains of PAA lose their protons and acquire a negative charge. Partially or wholly deprotonated PAAs are polyelectrolytes, with the ability to absorb and retain water and swell to many times their original volume. See more Poly(acrylic acid) (PAA; trade name Carbomer) is a polymer with the formula (CH2-CHCO2H)n. It is a derivative of acrylic acid (CH2=CHCO2H). In addition to the homopolymers, a variety of copolymers and crosslinked … See more PAA is produced by free radical polymerization. Initiators include potassium persulfate and AIBN. Polyacrylic acid is a polyolefin. It can be viewed as polyethylene with carboxylic acid (CO2H) substituents on alternating carbons. Owing to … See more Dry PAAs are sold as white, fluffy powders. In the dry powder form, the positively charged sodium ions are bound to the See more About 1,600,000,000 kg were produced in 2008. See more Polyacrylic acid is a weak anionic polyelectrolyte, whose degree of ionisation is dependent on solution pH. In its non-ionised form at low pHs, PAA may associate with various non-ionic polymers (such as polyethylene oxide, poly-N-vinyl pyrrolidone, … See more Absorbent PAA is widely used in dispersants and since the molecular weight has a significant impact on the rheological properties and … See more evergreen medical clinic hours
