In this paper, we report novel crosslinking systems for surfactant-free artificial latexes based on anhydride-containing polymers. Surfactant-free latexes with average particle diameters of about 150nm and a ζ-potential of −70mV have been successfully obtained from anhydride-containing polymers with various T g s and polarities, including poly(octadecene-alt-maleic anhydride) (POMA) and maleinized...
A two-gradient self-consistent-field theory using the discretisation scheme of Scheutjens and Fleer is applied to predict the structure in the lateral direction of the free surface of a microphase-separated compressible polymeric melt. A fluorinated block copolymer system is described in which parameters are chosen such that the fluorinated units preferentially segregate at the free surface. As soon...
We describe the preparation of surfactant-free artificial latexes on the basis of poly(styrene-alt-maleic anhydride) (SMA) copolymers. The SMA copolymers were first partially alkyl-imidized and then partially ammonolyzed in acetone. Upon adding to water and after the removal of acetone, the modified copolymers formed stable latexes, with a diameter of ∼150nm and a PDI<0.2. In the absence of alkyl...
