"With these newinvestments we will be the first company to produce acrylic acidand superabsorbent polymers in South America, which will enableus to better serve our customers, further foster our position inthese markets and open up additional opportunities for ourbuisnesses in South America," he says.

Together with the pilot plant for 3-HP, operated by Cargill and supported by Novozymes, this will further support BASF’s plans for fast market entry of superabsorbent polymers derived from bio-based acrylic acid.
Any tie-up with the Swiss group would be expected to trigger considerable antitrust related asset sales.
BASF is also a potential buyer of Syngenta's seed business should Monsanto agree to a deal with Syngenta and then sell its seed business to allay antitrust concerns, sources have previously told Reuters.
The German group, which has oil and gas operations and makes products including coatings, catalytic converters and super absorbers for diapers, trades at about 8.4 times core earnings compared with Syngenta’s multiple of 15.9, according to StarMine data.
Superabsorbent Polymers by Damir Karimov on Prezi
Other materials are also used to make a superabsorbent polymer, such as polyacrylamide copolymer, ethlyene maleic anhydride copolymer, cross-linked carboxymethylcellulose, polyvinyl alcohol copolymers, cross-linked polyethylene oxide, and starch grafted copolymer of polyacrylonitrile (PAN) to name a few. The starch-grated PAN is one of the oldest SAP forms created. For the first few decades of commercial SAP production, most products were starch-grafted products. This type of SAP was gradually discontinued in the late 1990's and virtually all commercial SAPs are made without starch.
Production of Superabsorbent Polymers - Waste Lock
Today superabsorbent polymers are made using one of three primary methods: (1) suspension polymerization, (2) solution polymerization or (3) gel polymerization. Each process has certain advantages over the others and there are trade-offs between them. All yield a consistent quality of product.
Production of Superabsorbent Polymers ..
Another benefit of these polymers – when dealing with waste containing metals – is the polycarboxylate (-COOH, -COONa) nature of the polymers. This –COOH group has a very high ion exchange capacity for soluble metal cations. Many wastes containing heavy metals such as Lead, Mercury and Chromium will pass the EPA Toxic Characteristic Leachate Procedure (TCLP) after solidification with Superabsorbent Polymers.
How do superabsorbent polymers work?
Another benefit of these polymers – when dealing with waste containing metals – is the polycarboxylate (-COOH, -COONa) nature of the polymers. This –COOH group has a very high ion exchange capacity for soluble metal cations. Many wastes containing RCRA metals will pass TCLP after solidification with Waste Lock® Superabsorbent Polymers.
How do superabsorbent polymers work
Superabsorbent Polymer is being used at many environmental sites to solidify waste so that it passes Paint Filter Test (EPA 9095). The polymer will absorb many times it weight in water with less than 1% increase in waste volume. By avoiding an increase in the waste volume, significant savings can results with fewer loads to ship and fewer yards of landfill disposal fees.
