Water-soluble Biocompatible Polymers: Poly(2-oxazoline)s
Poly(2-oxazoline)s are biocompatible and non-immunogenic pseudo-polypeptide-structured polymers. ULTROXA® Poly(2-methyl-2-oxazoline) [P2506], a highly-defined polymer with narrow molar mass distribution developed by Ghent University, is more hydrophilic than poly(ethylene glycol) (PEG). ULTROXA® Poly(2-propyl-2-oxazoline) [P2508] transitions to a hydrophobic state in water when heated. Poly(2-oxazoline)s are applicable to surface coating, drug delivery systems, and thermoresponsive material.
Advantage
• Biocompatible and non-immunogenic pseudo-polypeptide structure
• P2506 is more hydrophilic than poly(ethylene glycol) (PEG).
• P2508 transitions to a hydrophobic state in water when heated. (Low Critical Solution Temperature (LCST) : ca. 25°C)
• P2506 is more hydrophilic than poly(ethylene glycol) (PEG).
