Solubilization of a graft copolymer comprising a hydrophobic poly(dodecyl-methacrylate) backbone and hydrophilic poly(ethylene glycol) monomethyl ether side chains in water/AOT/cyclohexane w/o microemulsions was rationalized in terms of the backbone dissolved in the continuous apolar phase and the side chains entrapped within the aqueous micellar cores [189],... 

A synthesis of comblike organoboron polymer/boron stabilized imidoanion hybrids was examined via reactions of poly(organoboron halides) with 1-hexylamine and oligo(ethylene oxide) monomethyl ether and subsequent neutralization with lithium hydride (scheme 8). The obtained polymers (10) were amorphous soft solids soluble in common organic solvents such as methanol, THF, and chloroform. In the nB-NMR spectra (Fig. 11), neutralization of the iminoborane unit with lithium hydride... 

Starting from the commercially available aldehyde (12), styrene (13) was prepared by a straightforward synthetic sequence (Scheme 11.3). Subsequent esterification of the phenol with succinate-derivatized poly(ethylene glycol) monomethyl ether (MeO-PEG) appended the styrene unit to approximately 50% of the free acid groups in (14). The loading in (15) was estimated by 500 MHz NMR spectroscopy to be about 0.1 mmol g . In a final step, the polymer-bound catalyst was ob-...

Polymer-supported liquid-phase synthesis was introduced for the preparation of oligosaccharides by Douglas, Whitheld and Krepinsky [99]. In their procedure, the carbohydrate is attached to the soluble polymer, poly(ethylene glycol)monomethyl ether (PEG), and all the chemical... 

A novel route to DHBC is outlined in Scheme 11. Reaction of TEMPO-ter-minated poly(VBC) with PEG-monomethyl ether results in reactive block copolymers 47, which can be converted readily to polymers 48 and 49 containing a cationic or a betainic block besides a PEG block [84]. 

Ionic polymers 120 containing a mesylate anion were prepared by the quaterniza-tion of poly(4-vinylpyridine/styrene) 118 with tri(ethylene glycol) monomesylate monomethyl ether 119. These polymers were used to immobilize OSO4, as shown in Scheme 3.33. The resultant polymer 122 showed excellent catalytic performance in the Sharpless asymmetric dihydroxylation of styrene derivatives [63]. For example, 123 was dihydroxylated to styrene glycol 124 in 88% yield with 99% ee.

An extension of the combinatorial synthesis in solution is achieved by the use of soluble polymeric supports [80, 81], which combines some of the advantages of chemistry in solution and on solid phase. The so-called liquid-phase combinatorial synthesis is based on the physical properties of poly (ethylene glycol) monomethyl ether. The polymer is soluble in a variety of aqueous and organic solvents, which allows reactions to be conducted in homogeneous phase whereas the propensity to crystallize in appropriate solvents facilitates the isolation and purification of the compound at each step of the combinatorial synthesis. 

Boron tribromide in methylene chloride or benzene is recommended for demethylation of polymethoxybenzophenones, where use of hydrogen bromide in acetic acid is often accompanied by cyclodehydration of the resulting poly-hydroxybenzophenones to give xanthones. However, unexpected difficulties were encountered in the case of 2,2, 3, 6-tetramethoxybenzophenone (1), where the major product (76% yield) was the monomethyl ether (2), the desired tetra-... 

The property levels of cresol free solvent based poly(ester-imide) enamels are inferior to the cresylic products. In Table 3 the cresylic poly(ester-imide) varnish, solved in a mixture of cresol and Solvesso and the cresol free varnish 1, solved in a mixture of diethyleneglycol monomethyl and monoethyl ether plus some small amounts of Solvesso have the same resin composition. The cresylic product is superior. The reason is that the preparation of the cresol free resin was made using diethyleneglycol monomethyl ether as solvent in the synthesis, causing a lower average molecular weight of the polymer. The cresol free po-...
