The word polyacrylamide and the acronym “PAM” are generic chemistry terms, referring to a broad class of compounds.There are hundreds of specific PAM formulations. They vary in polymer chain length and number and kinds of functional group substitutions as well as molecular conformation, the most important conformation variation being linear or cross‐linked conformation.

- Which cationic polymers are used in water treatment?
- None. DADMAC is the foundational chemical for the family of cationic polymers, PolyDADMACs, which are used in water treatment as coagulants and dewatering agents. Water treatment is a primary use of PolyDADMACs, but not DADMACs. DADMAC is an intermediate in the production of resins and polymers.
- Can cationic polymer purification reduce nitrosodimethylamine (NDMA) formation?
- The present study shows the contributions of cationic polymer to nitrosodimethylamine (NDMA) formation, and how polyDADMAC purification can dramatically reduce NDMA formation. Diaultrafiltration of polyDADMAC to remove low molecular polymer residuals reduced NDMA formation by over greater than 50% without impacting other water treatment goals.
- Do cationic polymers contribute to NDMA formation in water treatment plants?
- 335 polyDADMAC solution represent a major portion of NDMA precursors. Thus, there may be 337 formation at water treatment facilities that use chloramine disinfectants. 340 flow pilot-tests. First, cationic polymers contribute to NDMA formation at water treatment plants 341 that utilize chloramine disinfectants.
- What is cationic polymeric surfactant - poly (diallyl dimethyl ammonium chloride-acrylamide)?
- In the present study, the cationic polymeric surfactant- poly (diallyl dimethyl ammonium chloride-acrylamide) P (DADMAC- co -AM) was synthesized using free radical aqueous solution copolymerization of two monomers with vinyl functionality viz. diallyl dimethyl ammonium chloride (DADMAC) and acrylamide (AM).
