“…Volet et al have described the synthesis and solution properties of semi-telechelic poly(2-methyl-2-oxazolines) (PMOz) bearing an n-dodecyl-or an n-octadecyl group at one chain end [475]. Telechelic PMOz with a perfluorooctyl group at one end and a hydrocarbon group 6-18 carbons long were prepared with a view towards the creation of multidomain micelles containing segregated fluorinated and hydrocarbon hydrophobic compartments [582]. Hydrophobically endmodified poly(2-ethyl-2-oxazolines) (PEOz) and poly(2-isopropyl-2-oxazolines) (PiPOz) bearing an n-octadecyl chain on both termini or on one chain end only were prepared by cationic ring-opening polymerization of 2-ethyl-2-oxazoline and 2-isopropyl-2-oxazoline, respectively, and subsequent end-group modification [583].…”

Numerous non-ionic thermally responsive homopolymers phase separate from their aqueous solutions upon heating. Far fewer neutral homopolymers are known to phase separate upon cooling. A systematic compilation of the polymers reported to exhibit thermoresponsive behaviour is presented in this review, including N-substituted poly[(meth)acrylamide]s, poly(N-vinylamide)s, poly(oxazoline)s, protein-related polymers, poly(ether)s, polymers based on amphiphilic balance, and elastin-like synthetic polymers. Basic properties of aqueous solutions of these polymers are briefly described.

“…The synthesis and self-assembly behavior of amphiphilic PMeOx with both fluorocarbon and hydrocarbon chain end functionalities was reported by Spiess and Nuyken et al giving rise to the formation multicompartment micelles containing two segregated spherical hydrophobic domains [78] or, at lower concentration, cylindrical micelles with a segregated cylindrical core [79]. Amphiphilic block copoly(2-oxazoline)s with a poly(2-perfluoroalkyl-2-oxazoline) hydrophobic block were demonstrated by Nuyken to aggregate into micellar structures in aqueous solution [80].…”

Bioinspired Poly(2-oxazoline)s

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.

“…Other amphiphilic polyoxazolines were prepared starting from initiators or terminating agents with long alkyl chains and hydrophilic 2-oxazoline [8,9]. Similar architectures were performed from perfluoro initiator [10]. Some examples of graft copolymers were also referred to poly(2-methyl-2-oxazoline) and phosphazene [11] or chitine [12].…”

. Nonionic polyoxazoline surfactants based on renewable source: Synthesis, surface and bulk properties. Reactive and Functional Polymers, Elsevier, 2009, 69, pp.643-649 Abstract: The synthesis of amphiphilic lipid-polyoxazoline based on copolymers (CO-POx n ) with narrow distribution has been achieved via cationic ring-opening polymerization of 2-methyl-2-oxazoline (MOx). Lipid-macroinitiator (COTs) was obtained from commercial castor oil (CO), widely renewable agricultural resource. CO-POx n with various length segments were synthesized from a macroinitiator COTs in order to investigate the effect of the length of the hydrophilic segment on the solution behavior of the nonionic polymer surfactants CO-POx n . The results showed that the critical micelle concentration rised with the increase of POx content and inversely surface tension decreased. The average size of aggregates of these structures suggested the formation of vesicles or nonspherical micelles. Star-shaped morphology of CO-POx n in solid state has also been observed using 2 environmental scanning electron microscopy (ESEM). Addionally energy dispersive X-ray (EDX) analysis demonstrated the presence of POx block in the concentric stripes of the texture.
