The technology for cleaning water-soluble polymers from hydrophobic contaminants uses water as a solvent, which is a cheap and harmless substance. Alternatively, in small quantities, cheap pH modifiers such as hydrochloric acid and sodium hydroxide.
Competitive advantage
- suitable for polymer contamination levels from 0.0005% to 0.1% of hydrophobic contaminants,
- capable of reducing hydrophobic contaminants level below 0.0001%,
- reprecipitation as an alternative method provides only a “rough purification” or a pre-purification,
- reprecipitation, unlike our method, requires usage of expensive ultrapure organic solvents,
- preparative chromatography as another alternative method is incomparably more expensive in terms of operational cost, equipment cost, and personnel cost.
Use of technology
- Purification of water-soluble polymers (neutral polymers, polyanions, polycations, pH-sensitive weak polyacids and polybases) and ionic and non-ionic monomers. For applications where purity is a must.
