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

A series of linear poly(ethylenimine) (L-PEI) containing varying amounts of cationic charge density in its backbone was produced by controlled hydrolysis of poly(2-ethyl-2-oxazoline) (PEtOz) for using as a nonviral DNA transfection agent. The effects of cationic charge density and molecular

Polymeric micelles based on amphiphilic block copolymers of poly(2-ethyl-2-oxazoline) (PEtOz) and poly(epsilon -caprolactone) (PCL) were prepared in an aqueous phase. The loading of paclitaxel into PEtOz-PCL micelles was confirmed by 1H-NMR spectra. Paclitaxel was efficiently loaded into PEtOz-PCL micelles using

New controlled drug-delivery systems are being explored to overcome the disadvantages of conventional dosage forms. For example, stimulated drug-delivery has been used to overcome the tolerance problems that occur with a constant delivery rate, to mimic the physiological pattern of

A new series of cationic, thermo-sensitive, and biodegradable poly(L-lactide)-poly(2-ethyl-2-oxazoline)-poly(L-lactide) (PLLA-PEOz-PLLA) triblock copolymers were synthesized by ring-opening polymerization. With increasing molecular weight and crystallinity of hydrophobic PLLA blocks, the critical micellization concentrations (CMC) occurred at lower concentration. The PLLA-PEOz-PLLA aqueous solution
