Polyethers and Polyoxazolines

The synthesis of well-defined polyethers by ROP has only been reported for a limited number of monomers that have enougji ring-strain to be readily opened, namely ethylene oxide, oxetane and THF. Moreover, the rather similar reactivity of the cyclic ether bonds and the ring-opened polymeric ether bonds in combination

Poly(ethylene oxide) is the most commonly used polymer in personal, home and health care applications, due its water solubihty in combination with a very low toxicity. These attractive properties of poly(ethylene oxide) can be ascribed to the distance between the alternating oxygen atoms in the chains that is in agreement with the hydrogen distances in hquid water allowing the formation of an extensive hydrogen-bonding network with water [12, 13].

Part 2 includes chapters on specific classes of cyclic monomers and their polymerization mechanisms and kinetics, their main (co)polymer architectures and related products, as well as current and future applications. Hence, siloxane-con-taining and sulfur-nitrogen-phosphorus-containing polymers are described in Chapters 3 and 4, respectively, while the polymerization of cyclic depsipeptides, ureas and urethanes, of polyethers and polyoxazolines, and of polyamides are detailed in Chapters 5, 6 and 7, respectively. Chapters 9, 10, 11 and 12 include details of polyesters prepared from either P-lactones, from dilactones, from larger lactones and from polycarbonates, while the polymerization of cycloalkanes is described in Chapter 13. It should be noted that, slightly out of place . Chapter 8 covers the subject of ring-opening metathesis polymerizahon. 

Cocondensation of macromers containing trialkoxysilyl groups with modified polystyrene (PS), polyoxazoline, polyimide, polyethylene glycol (PEG), polyether-ketones, polymethyl methacrylate, and derivatives of polytetramethylene oxide was established as convenient procedure for the preparation of telechelic polymer net-...
