It is a cheap and easily available form of the polymer. It is used for many applications such as electronics, medical, optical, automotive parts, and packaging of consumables. A large number of goods produced using PS are formed by injection
- Which comonomer is used for the production of anionic polyacrylamides?
- The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid. These anionic polymers can be prepared as various mono- and divalent metal salts and other positively charged inorganic and organic counterions of the polymerization of acrylic acid with acrylamide (see Fig. 34.4 ).
- What type of polyacrylamide is used in oil industry?
- The polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers. The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers .
- How are polyacrylamide gels prepared?
- Polyacrylamide gels are prepared by free radical polymerization of acrylamide and a comonomer crosslinker such as bis-acrylamide. Polymerization is initiated by ammonium persulfate (APS) with tetramethylethylenediamine (TEMED) as the catalyst (see figure below).
- What is an anionic polyacrylamide?
- Anionic polyacrylamides make up the largest portion of the polyacrylamide market. The polymers can be prepared over a wide range of anionic charges and molecular weights (1000 to > 20,000,000 molecular weight). The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid.
