“…Amphiphilic poly(2-oxazoline) block copolymers were already recognized as promising non-ionic surfactants by the group of Kobayashi in 1986 [54]. Naka et al and Binder et al demonstrated that the micellization of such poly(2-oxazoline) block copolymers can be influenced by variation of the hydrophobic poly(2-oxazoline) block [55,56].…”

Poly(2-oxazoline)s are regarded as pseudopeptides, thus bioinspired polymers, due to their structural relationship to polypeptides. Materials and solution properties can be tuned by varying the side-chain (hydrophilic-hydrophobic, chiral, bioorganic, etc.), opening the way to advanced stimulus-responsive materials and complex colloidal structures. The bioinspired -smart‖ solution and aggregation behavior of poly(2-oxazoline)s in aqueous environments are discussed in this review.

“…Several 2‐oxazolines bearing cycloaliphatic R side‐chains have been described, with strained cycles,118 bicycles, or tricycles 98. 2‐Oxazolines with aromatic R side groups have also been synthesized19 with various substituents,29, 98, 105, 119 including perfluoro groups 103, 120. Other aromatic systems have been investigated with furanyl103, 121 and carbazoyl cycles.…”

“…Functionalization of the POx chain ends is obtained by using functional initiators27 or terminating agents,28 or via the use of 2‐R‐2‐oxazolines where R represents a functional pendant group29 (Figure 1). It is also important to notice that the functional groups of the initiator or monomer interfere in some cases with the cationic ring‐opening polymerization of 2‐R‐2‐oxazoline 30.…”

Polyoxazolines (POx) are increasingly studied as polymeric building blocks due to the possibility of affording tunable properties. Additionally, as it was proved that biocompatibility and stealth behavior of POx are similar to that of poly(ethylene glycol) (PEG), it became challenging to develop polyoxazoline-based (co)polymers. Even if POx have a lot of advantages, they also show an important drawback as it is to date impossible to prepare high molecular weight polyoxazolines, with low polydispersity indexes. So, it appears important to judiciously functionalize them. This review covers the multiple ways of functionalization of polyoxazolines.The use of functional initiators, functional terminating agents, and 2-R-2-oxazolines with R functional side group is detailed. In conclusion, some perspectives on POxfunctionalizations are also reported, with functions permitting selective "click" reactions.

“…NaAlg is a biodegradable polymer used extensively in drug delivery applications (Aminabhavi, Kulkarni, Soppimath, Dave, & Mehta, 1999;Downs, Robertson, Riss, & Plunkett, 1992;Babu et al, 2006). Chitosan (CS) which can be obtained from the deacetylation of chitin is one of the most facile polymers, whose structure can be modified chemically (Park, You, Park, Haam, & Kim, 2001;Binder & Heinrich, 2000). It is more widely used in biomedical applications than chitin itself because it degrades in an aqueous environment because of the presence of hydroxyl and aminogroups which can be readily modified (Kang, Choi, & Kweon, 1999;Peniche et al, 1999).…”
