Description

Application

This Poly(2-ethyl-2-oxazoline) polymer is amorphous and water soluble with good temperature stability. Jordan and coworkers showed biocompatibility, no accumulation in tissue, and rapid clearance from the bloodstream1. End-group modified poly(2-ethyl-2-oxazoline)s have been conjugated to peptides2, and were shown as versatile alternatives to poly(ethylene glycol) (PEG) for both protein and small drug conjugation3.

Potential substitute for poly(vinyl alcohol) and poly(vinyl pyrrolidone). Sometimes it is used as an adhesion promoter in coatings. This is also sometimes used in heat sealing and remoistenable hot-melt adhesives. N-propionyl substituted linear polyethylenimine

Caractéristiques et avantages

Nonionic, water-soluble thermoplastic. Better heat stability than poly(vinyl alcohol). Good melt flow, shear stability and Newtonian characteristics. Water is a room temperature Theta solvent.
