  • What is anionic polyacrylamide (Apam)?
  • 1. Introduction Anionic polyacrylamide (APAM) is a kind of organic high-molecular polymer with high hydrophilicity and viscosity, which is easily dissolved in water [ , , ].
  • What is the atomic percentage of Apam?
  • And the atomic percentage values are listed in Table 3. Meanwhile, the theoretical molecular formation of APAM and APAM-T is (C 3 H 5 ON) 8 (C 3 H 5 SO 3 Na) 2, when the dosage of SAS in the total monomer is 20 %, O/C = 0.467, N/C and S/C = 0.667. It coincided with the result of XPS analysis approximately.
  • Can UV-initiated template polymerization prepare a novel anionic polyacrylamide with a microblock structure?
  • E-mail: zhl6512@126.com; Fax: +86 23 65120827; Tel: +86 23 65120827 Ultraviolet (UV)-initiated template polymerization (UTP) was used as a feasible strategy to prepare a novel anionic polyacrylamide (APAM) with a microblock structure.
  • Is Apam a uniform polymer?
  • The polyacrylamide is a uniform and unitary polymer. PAM has a neat smooth surface as its SEM images unfold at 2500x and 4000x. However, the surface of APAM was much rougher. Hills and valleys could be observed in its SEM images due to the interaction of chemical groups between AM and SAS.
