Panoramica

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 bloodstream. End-group modified poly(2-ethyl-2-oxazoline)s have been conjugated to peptides, and were shown as versatile alternatives to poly(ethylene glycol) (PEG) for both protein and small drug conjugation. Potential substitute for poly(vinyl alcohol) and poly(vinyl pyrrolidone). Adhesion promoter in coatings. Heat sealing and remoistenable hot-melt adhesive

softening point 110-120 °C (Vicat, ASTM D 1525-82)
