Monomers (AA & AMPS) are dissolved and purified to stringent standards (<0.5% total free monomer).
Controlled radical polymerization in a reactor, under inert atmosphere (N₂), ensures narrow molecular distribution.
Neutralization adjusts pH and controls side reactions; purification (including microfiltration) removes salts and volatiles.
Comprehensive quality control includes: GPC, IC, HPLC analyses, viscosity measurement (ISO/ANSI methods).
Final packaging follows ISO 9001 and ANSI/NSF-60 to guarantee water contact safety and long shelf life (≥12 months sealed).
