설명

애플리케이션

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

특징 및 장점

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.

물리적 형태

N-propionyl substituted linear polyethylenimine
