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

Features and Benefits

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.

This paper reports an FT-IR study of blends of poly(mono-n-alkyl itaconates) with poly(N,N-dimethylacrylamide) (PDMA) and poly(ethyloxazoline) (PEOX). Strong hydrogen bonding has been found, and both polybases have shown similar acceptor strengths. Derivative techniques show asymmetric profiles for the free carbonyl

Poly(2-oxazoline)s (POx) in Biomedical Applications

Poly(2-oxazoline)s (POx) can be viewed as conformational isomers of polypeptides. They are synthesized via living cationic ringopening polymerization (LCROP) of 2-oxazolines and were almost simultaneously discovered in 1966 by the groups of Litt, Tomalia, Fukui and Seeliger.

Poly(2-isopropyl-2-oxazoline)-based Multimodal Stimuli-responsive Functional Materials

Based on the temperature properties of PiPrOxs, we have recently developed several multimodal stimuli-responsive polymeric systems. This review will briefly show recent developments of PiPrOx-based functional stimuli-responsive polymers.

Poly(2-Oxazoline)s: The Versatile Polymer Platform for Biomedicine

The introduction of polymers into the biomedical field has opened new avenues in tissue engineering, implant design, biosensing, and drug delivery.

Functional Polymers for Biomedical Applications

Wide range of functional polymers for biomedical applications have been synthesized and structurally characterized. Several classes of polymers including biodegradable polymers, hydrophilic & amphiphilic polymers, and stimuli responsive polymers have been prepared using controlled and directed functionalization via "living" polymerization such as RAFT, ionic and ring opening polymerization. Selected polymers have been studied for their structure-properties relationship. "

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
