Publikováno v: Macromolecules. 38:8308-8315

Hyperbranched poly(ethylenimine) (PEI) with amino groups or carbohydrate terminal groups have been used as support materials for metal nanoparticles (i.e., Cu, Ag, Au, and Pt) in water. Various parameters have been optimized, such as pH, concentratio

Water-soluble copolymers: 66. Phase transfer studies of structural and environmental effects on domain organization in aqueous solutions of hydrophobically modified poly(sodium maleate-alt-ethyl vinyl ether)s

Autor: Charles L. McCormick, Michael C. Kramer, Yuxin Hu, Jamie R. Steger

Publikováno v: Polymer. 37:4539-4546

Hydrophobically modified, water-soluble terpolymers based on maleic anhydride and ethyl vinyl ether were evaluated for their ability to act as a host for hydrophobic molecules in water. Alternating copolymers of maleic anhydride and ethyl vinyl ether

Water-Soluble Copolymers. 62. Nonradiative Energy Transfer Studies of pH- and Salt-Responsive Associations in Hydrophobically Modified, Hydrolyzed Maleic Anhydride-Ethyl Vinyl Ether Copolymers

Autor: Yuxin Hu, Chase J. Boudreaux, Michael C. Kramer, Charles L. McCormick

Publikováno v: Macromolecules. 28:7100-7106

A series of labeled, hydrophobically modified polymers based on the alternating copolymer of maleic anhydride and ethyl vinyl ether (MAEVE) has been synthesized to specifically address the issue of differences in domain organization of closed, polyso

Water-Soluble Copolymers. 63. Rheological and Photophysical Studies on the Associative Properties of Pyrene-Labeled Poly[acrylamide-co-sodium 11-(acrylamido)undecanoate]

Autor: Cynthia G. Welch, Jamie R. Steger, Michael C. Kramer, Charles L. McCormick

Publikováno v: Macromolecules. 28:5248-5254

The synthesis, rheological, and fluorescence properties of a novel water-soluble polymer based on a micelle-forming monomer are reported. Sodium 11-(acrylamido)undecanoate (SA), a surface-active monomer, copolymerizes readily with acrylamide (AM) to
