    A new anionic, hydrolysis-resistant polymerizable surfactant: synthesis and polymerization (1999)
    Springer
    Colloid & polymer science 277 (1999), S. 792-797

    Thema: Chemie und Pharmazie , Maschinenbau
    Notizen: Abstract The synthesis and some surfactant properties of a new type of sulfonated anionic monomer which is useful for free-radical polymerization are described. The monomer is based on the isobutenyl moiety as a reactive group. Higher homologues behave as polymerizable surfactants (“surfmers”). Copolymerization with a number of standard monomers is possible, as well as homopolymerization under micellar conditions.

    Monolayers of rod-shaped and disc-shaped liquid crystalline compounds at the air-water interface (1986)
    Springer
    Colloid & polymer science 264 (1986), S. 659-667 
    Details
    ISSN: 1435-1536
    Schlagwort(e): Monolayers ; liquid crystals ; discotics
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Chemie und Pharmazie , Maschinenbau
    Notizen: Abstract Calamitic (rod-shaped) and discotic (disc-shaped) thermotropic liquid crystalline (LC) compounds were spread at the air-water interface, and their ability to form monolayers was studied. The calamitic LCs investigated were found to form monolayers which behave analogously to conventional amphiphiles such as fatty acids. The spreading of the discotic LCs produced monolayers as well, but with a behaviour different from classical amphiphiles. The areas occupied per molecule are too small to allow the contact of all hydrophilic groups with the water surface and the packing of all hydrophobic chains. Various molecular arrangements of the discotics at the water surface to fit the spreading data are discussed.

    Polysoaps with fluorocarbon hydrophobic chains (1995)
    Springer
    Colloid & polymer science 273 (1995), S. 1138-1143 
    Details
    ISSN: 1435-1536
    Schlagwort(e): Amphiphilic polymers ; fluorocarbon polymers ; associating polymers ; polysoaps
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Chemie und Pharmazie , Maschinenbau
    Notizen: Abstract A series of amphiphilic copolymers is prepared by copolymerization of choline methacrylate with 1,1,2,2-tetrahydroperfluorooctyl methacrylate in varying amounts. The copolymers bearing fluorocarbon chains are studied concerning their effects on viscosity, solubilization and surface activity in aqueous solution, exhibiting a general behavior characteristic for polysoaps. The results are compared with the ones obtained for an analogous series of amphiphilic copolymers bearing hydrocarbon chains.

    Solubilization by polysoaps (1994)
    Springer
    Colloid & polymer science 272 (1994), S. 1118-1128 
    Details
    ISSN: 1435-1536
    Schlagwort(e): Micellar polymers ; polysoaps ; solubilization
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Chemie und Pharmazie , Maschinenbau
    Notizen: Abstract The aqueous solubilization power of several series of micellar homopolymers and copolymers (“polysoaps”) is investigated. Using five insoluble or poorly water-soluble dyes, comparisons of the capacities are made with respect ot the influence of structural variables such as the polymer backbone, the polymer geometry, the comonomer content, and the charge of the hydrophilic group. Some guidelines for polysoap structures suited for efficient solubilization are established. Noteworthy is that the solubilization capacities of the polysoaps are neither linked to the ability to reduce the surface tension of water, nor to the polarity of the solubilization sites deduced from spectroscopic probes.
