We have SAP(polyacrylate sodium)& SAP(polyacrylate potassium).
A series of polyacrylic acids and their salts with a range of molecular weights used as dispersing agents in a wide number of industrial applications to eliminate inorganic deposits or reduce the viscosity of inorganic slurries.
Synthesis and characterization of polyacrylate modified …
The inhibition of the crystal growth along the directions corresponding to the crystallographic axes is almost isotropic and indicates no preferential regular interaction of polyacrylate with the structure of OCP.
Superabsorbent polymers are now commonly made from the polymerization of acrylic acid blended with sodium hydroxide in the presence of an initiator to form a poly-acrylic acid sodium salt (Sodium Polyacrylate). This polymer is the most common type of SAP made in the world today.
Swelling–Contraction of Sodium Polyacrylate ..
Physical properties are for the acid form of the polymer.
The recommendations on this Card also apply to (polyacrylic acid, CAS# 9003-01-4).
Synthesis and Properties of Polyacrylate Emulsion …
A mixture of glacial acrylic acid (GAA), water, cross-linking agents and UV initiator chemicals are blended and placed either on a moving belt or in large tubs. The liquid mixture then goes into a "reactor" which is a long chamber with a series of strong UV lights. The UV radiation drives the polymerization and cross-linking reactions. The resulting "logs" are sticky gels containing 60-70% water. The logs are shredded or ground and placed in various sorts of driers. Additional cross-linking agent may be sprayed on the particles' surface; this "surface cross-linking" increases the product's ability to swell under pressure -- a property measured as Absorbency Under Load (AUL) or Absorbency Against Pressure (AAP). The dried polymer particles are then screened for proper particle size distribution and packaging. The Gel Polymerization (GP) method is currently the most popular method for making the sodium polyacrylate superabsorbent polymers now used in baby diapers and other disposable hygienic articles.

SODIUM POLYACRYLATE by Cherri B. on Prezi
We recommend as our workhorse dispersant of choice, but some applications see increased benefit from slightly different polymer chain lengths. To that end we offer a lower () and higher () molecular weight product. For applications requiring a significantly higher molecular weight, we offer . We also offer ammonium polyacrylate and the un-neutralised polyacrylic acids. Other salts can be provided to special order.
