“…An interesting study has been reported of macrocycles in which two additional groups containing OH sites are attached to two nitrogens of diaza crown ethers. 234 The results indicate that K values for complexes of A215C5 (2.1) with bivalent metal cations such as Ca2+, Sr2+, and Ba2+ increase by factors of 85, 89, and 30, respectively. The same trend is observed in the case of the complexes of A218C6 (2.2) and its derivatives.…”

“…The decreased M w with PEO-MA is attributed to both the increased contribution of the water-phase polymerization and the chain transfer to PEO units. [4][5][6]21 At high macromonometer concentration, the water-phase polymerization produces a high fraction of the saturated graft copolymer of lower molecular weight. 22 The higher the macromonomer concentration, the higher the chain transfer efficiency and the lower the molecular weight.…”

The graft copolymers (polystyrene‐graft‐polyoxyethylene) (PSt‐graft‐PEO) were prepared by the radical dispersion copolymerization of methacryloyl (MA)‐terminated PEO macromonomer and styrene. By means of size‐exclusion chromatography, liquid chromatography at the critical adsorption point, and light scattering, the molecular weight parameters and the solution properties of PSt‐graft‐PEO were investigated. The apparent average molecular weight and the molecular weight distribution (MWD) of graft copolymers were found to decrease with increasing molecular weight of PEO‐MA macromonomer. This decreased molecular weight was attributed to the chain transfer to PEO unit and increased contribution of the solution polymerization. The broad MWD varied with the ratio of the polymerization in the continuous phase and the polymer particles. The number of PEO grafts per PSt backbone decreased with increasing molecular weight of the PSt‐graft‐PEO copolymer, which was attributed to the intramolecular association of PEO segments. The intrinsic viscosity or the coil size of graft copolymer molecules varied with temperature as a result of the dehydration of PEO segments. © 1999 John Wiley & Sons, Inc.
