    Notes: 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.

    Polysoaps with fluorocarbon hydrophobic chains (1995)
    Springer
    Colloid & polymer science 273 (1995), S. 1138-1143 
    Details
    ISSN: 1435-1536
    Keywords: Amphiphilic polymers ; fluorocarbon polymers ; associating polymers ; polysoaps

    Notes: 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.

    Amphiphilic hyperbranched polyelectrolytes: a new type of polysoap (1999)
    Springer
    Colloid & polymer science 277 (1999), S. 519-527

    ISSN: 1435-1536
    Keywords: Key words Hyperbranched polymer ; Polyelectrolyte ; Polysoap ; Micellar polymer ; Ionene

    Notes: Abstract Hyperbranched hydrophobized polyelectrolytes of the ionene type are prepared. They are investigated as a new type of polysoap, with respect to viscosifying behaviour, surface activity and solubilization power. Compared to linear analogues, the viscosifying effect is reduced. Compared to classical polysoap architectures, such as analogous “tail-end-type” and “head-type” polysoaps, the hyperbranched polysoaps behave rather similarly to the “head-type” ones: they exhibit notable surface activity, whereas the solubilization capacity is moderate only.

    Solubilization by polysoaps (1994)
    Springer
    Colloid & polymer science 272 (1994), S. 1118-1128 
    Details
    ISSN: 1435-1536
    Keywords: Micellar polymers ; polysoaps ; solubilization
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: 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.

    Oriented supramolecular systems-polymeric monolayers and multilayers from prepolymerized amphiphiles (1986)

    Notes: Oriented polymeric membranes were originally prepared by polymerization or polycondensation of preoriented monomers. The introduction of hydrophilic spacer groups into the polymeric amphiphiles allowed the formation of highly ordered systems (monolayers, liposomes, multilayers) from prepolymerized amphiphiles: due to the partial decoupling of the different mobilities and orientation tendencies of the polymer chain and the amphiphilic side groups, these polymers are able to self-organize. In monolayer experiments the high order of these membranes could be demonstrated by their surface pressure area-diagrams. In addition the combination of order and mobility of these spacer groups containing polymeric amphiphiles allowed the formation of Langmuir-Blodgett-multilyers with a high layer correlation. Thus, disturbancies in highly oriented layers can be avoided normally taking place during the polymerization reaction (e.g. contractions) or oriented monomeric layers.
