SUPERABSORBENT POLYMER (POLY ACRYLIC ACID BASED)
[EIRI/EDPR/1662] J.C. 478 (INR), 479 (US$)
INTRODUCTION
Superabsorbent polymers are primarily used as an absorbent for water and aqueous solutions for diapers, adult incontinence products, feminine hygiene products and similar applications. Undoubtedly in these applications, superabsorbent materials will replace traditional absorbent materials such as cloth, cotton, paper wadding, and cellulose fiber.
Commercial production of superabsorbent polymers began in Japan in 1978 for use in feminine napkins. This early superabsorbent was a cross linked starch-g-polyacrylate. Polyacrylic acids eventually replaced earlier super absorbents, and is the primary polymer employed for superabsorbent polymers today. In 1980, European countries further developed the superabsorbent polymer for use in baby diapers. This first diapers employing this technology used only a small amount of polymer, approximately 1-2 g. In 1983, a thinner diaper using 4-5 grams of polymer and less fluff was marketed in Japan.
The use of superabsorbent polymers revolutionized the diaper industry. Diaper manufacturers began to design diapers to take advantage of the amazing liquid retention ability of the polymer. Superabsorbent polymers absorb, and retain under a slight mechanical pressure, about 30 times their weight in urine. The swollen gel holds the liquid in a solid, rubbery state and prevents the liquid from leaking onto the baby’s skin and clothing.
Superabsorbent polymers are prepared from acrylic acid and a cross linker by solution or suspension polymerization. The type and quantity of cross linker control both the swelling capacity and gel modulus. The synthesis and use of cross linked polyacrylate super absorbents have been a popular topic in the polymer literature. However, very little information about manufacturing processes has been given due to its proprietary content.
