“…Copolymer (39, R CH 3 ) shows good antielectrostatic properties when blended with nylon-6 (66). α,ω-Dihaloalkanes derived from aromatic vinyl polymers induce the polymerization of 2-methyl-2-oxazoline to yield ABA block copolymers with the vinyl polymers as the B block (67). Poly(ethylene glycol adipate) has been used as the B block, and 2-oxazoline monomers with electron donor or electron acceptor groups provide the A block (68,69).…”

“…Volet et al 39 disclosed the synthesis of diblock copolymers by a consecutive cationic polymerization of isobutyl vinyl ether and MOx in a one-pot process using a hydrogen iodide-iodine system as initiator. Besides this, the synthesis of block copolymers of aromatic vinyl compounds and MOx was carried out by Morishima et al 40 in four steps by a combination of anionic polymerization, chain-end transformation, halogen exchange, and then CROP of MOx. Seung and Young [41][42][43] obtained block copolymers by CROP of MOx using polymers bearing iodine end chain as macroinitiator.…”

“…11 Polyoxazolines are prepared by living cationic ring-opening polymerization (CROP) of 2-oxazoline. 12 Their CROP has been combined with living anionic, 13,14 other cationic 15,16 polymerization techniques, and ring-opening polymerization of carboxyanhydride, 17,18 or lactide. 19 But few reports describe the combination of CROP with controlled radical techniques, such as atom transfer radical polymerization 20 and nitroxide-mediated radical polymerization (NMP), which is also a valuable approach to obtain precise architectures.…”

The synthesis of two well‐defined 2,2,5‐trimethyl‐4‐phenyl‐3‐azahexane‐3‐nitroxide‐terminated poly(2‐methyl‐2‐oxazoline) with narrow dispersity (Mw/Mn = 1.1) has been achieved for the first time. The insertion of the alkoxyamine end groups at one or both ends of poly(2‐methyl‐2‐oxazoline) (PMEOX) chains has been successfully done using a method based on “terminating reagent method.” These macroinitiators have molecular weights ranging from 6.3 × 103 to 9.4 × 103 g mol−1. In contrast, attempt to introduce the alkoxyamine group at one end of PMEOX chain through the “initiator method” has furnished a mixture of alkoxyamine‐graft polyoxazolines because of rearrangement of alkoxyamine occurring during the synthesis of PMEOX. The macroinitiators obtained by terminating reagent method have been used successfully for polymerization of styrene by nitroxide‐mediated radical polymerization (NMP), which exhibited all the expected features of a controlled system. The control of NMP has been proved by a good agreement between theoretical and experimental molecular weights and by narrow dispersity (Mw/Mn < 1.2). Different types of well‐defined multiblock copolymers have been prepared: diblock copolymers poly[(2‐methyl‐2‐oxazoline)‐b‐(styrene)] (PMEOX‐b‐PS) and, for the first time, triblock copolymers poly[(styrene)‐b‐(2‐methyl‐2‐oxazoline)‐b‐(styrene)] (PS‐b‐PMEOX‐b‐PS). © 2011 Wiley Periodicals, Inc.
