Poly -block-oligo ethylene

One of the most popular types of soluble macromolecular metal complexes used in reactions in aqueous media are complexes of terminally modified poly- and oligo(ethylene oxide)s and block copolymers of ethylene oxide and propylene oxide. The main advantages of using these polymers as ligands are the following ...

Trialkylsilyl-protected oligo(ethylene glycol)methacrylates, 2- 2- (tert-butyldimethylsilyl)oxy]ethoxy ethyl methacrylate (1), and 2- 2-[2-[(ferf-butyldimethylsilyl)oxy] ethoxy] ethoxy ethyl methacrylate (2) (Scheme 7) were used for the synthesis of amphiphilic block copolymers by anionic poly-... 

The triblock terpolymer polypropylene oxide)-h-poly[2-(dimethylami-no)ethyl methacrylate]-b-poly[oligo(ethylene glycol) methacrylate], PPO-fc-PDMAEMA-fc-POEGMA, was prepared using the PPO macroinitiator followed by the addition of CuCl, HMTETA, and DMAEMA for the polymerization of the second block and finally OEGMA for the synthesis of the final product (Scheme 54) [128]. 

Investigations were also made into surface nanostructures and their reconstruction behavior, by altering the outer environment using a series of block copolymers, namely PS-f)-poly(2-(perfluorooctyl)ethyl methacrylate) [96], PS-b-P(HEMA) [106, 107], and PS-f)-poly[(oligo(ethylene glycol) alkyl ether methacrylate), synthesized by anionic block copolymerization [116-120]. 

Control of macroscopic orientation of the microphase-segregated structures leads to efficient anisotropic conduction of proton and ions [132-139], Proton conductive supramolecular materials have been prepared by using microphase segregation of supramolecular block polymers 42 consisting of poly(styrene)- tock-(4-vinylpyridine), toluene sulfonic acid, and 3-pentadecyl phenol (Figure 31) [137]. Ionic conductive side-chain polymers have been obtained by complexation of oligo(ethylene oxide)sulfonic acid with poIy(styrene)-fe/ock-(4-vinylpyridine) [139]. 

Amphiphilic Block Copolymers Lim and coworkers reported the formation of hydrated micelles stabilized by a poly(l,l,2,2-tetrahydroperfluorooctyl methacrylate)-based copolymers incorporating either poly(A/,A-dimethylaminoethyl methacrylate) (PDMAEMA) (see Figure 13.26a) or poly(oligo(ethylene glycol) methacrylate) (POEGMA) hydrophilic blocks (see Figure 13.26b).
