Technology Information

Control of Physical Properties of Polyacrylamide (PAM) Resins Using Our Controlled Radical Polymerization Technology

Characteristics

  • Possible to control molecular weight, molecular weight distribution, size, structure (degree of branching) and distribution of ionic moiety in PAM
  • Possible to control formation ability of poly ion complex of amphoteric PAM by using technology described above
