  • What is a polyacrylate comonomer?
  • Polyacrylates Polyacrylates are a class of anionically charged polyelectrolytes where acrylic acid and its salts are the primary monomer used in their preparation. Other comonomers can be and are incorporated into the polymer chain to alter the molecular weight and physical properties and performance of the resulting polymers.
  • How is polyacrylamide a hydrolyzed polymer?
  • The process generally involves the addition of a strong base to a homopolymer of polyacrylamide. This can be done in an aqueous solution, inverse emulsion. Recently, a process to produce dry forms of hydrolyzed polyacrylamide has been developed. This allows for the preparation of very high-molecular-weight anionic polymers.
  • What are the different types of polyacrylamide?
  • There is a wide range of diverse solution polyacrylamides available in the commercial marketplace (anionic, cationic, and nonionic). They cover a wide range of charges and can range in molecular weights from the thousands to one or two million Daltons.
  • What are the key features of polymeric polyelectrolytes?
  • The key features or operations of polymeric polyelectrolytes are in their ability to use their charged character either to cause precipitation and separation of suspended materials in solution through charge neutralization or the suspension of particles in solution via charge repulsion .
