Polyacrylic Acid (Sodium)-Agent of Toagosei Group
A polymer of acrylic acid (sodium) is an anionic polymer containing a large number of carboxyl groups (-COOH) in the molecule. The linear polyacrylic acid (sodium) aqueous solution can form a viscous and adhesive non-stretchable gel. Through the combination of various polyacrylic acid (sodium) and the use of a cross-linking agent, a water-resistant gel having hardness and adhesion is produced.
This water-resistant gel can be used not only as a pap patch for pharmaceuticals, but also for a wide range of non-medical products such as antipyretic and pap patches, as well as cosmetics.
Polyacrylic acid (sodium) products are derived from the polymerization of acrylic acid. This series of products can be obtained due to different degrees of neutralization. Its composition can be represented by the following structure:
Because the degree of polymerization m and n are different, polyacrylic acid (n = 0), sodium polyacrylate (m = 0), and partially neutralized sodium polyacrylate products (m / n) can be obtained.
