New Papers are published

Our work entitled “Solvent-Responsive Self-Assembly of Amphiphilic Invertible Polymers Determined with SANS”authors Olena Kudina, Ananiy Kohut, Ihor Tarnavchyk, Ivan Hevus, and Andriy Voronov, was recently published in Langmuir. In this work we report about using small-angle neutron scattering to obtain a quantitative description of the invertible micellar assemblies (IMAs) formed by amphiphilic invertible polymers (AIPs). Our experiments demonstrated that AIP unimers self-assemble into IMAs in aqueous solution, predominantly through interactions between the hydrophobic moieties of macromolecules. The hydrophobic effect (or solvophobic interaction) was shown to be the major driving force for self-assembly.

Stanislav Voronov, Ananiy Kohut, Ihor Tarnavchyk and Andriy Voronov are authors of other published review article entitled “Advances in Reactive Polymeric Surfactants for Interface Modification” in Current Opinion in Colloid & Interface Science. In this review publication we described recent advances in the synthesis of reactive polymeric surfactants (RPSs) and the application of 14 different RPSs for the modification of the interface in aqueous dispersions of polymers, reinforced polymer-based composites, and polymer blends.

Finally, the manuscript “Reinforcing Latex Coatings with Reactive Latex Particles”, authors Andriy Popadyuk, Ihor Tarnavchyk, Nadiya Popadyuk, Ananiy Kohut, Volodymyr Samaryk, Stanislav Voronov, Andriy Voronov, is accepted for publication in a special issue of Progress in Organic Coatings entitled “Festschrift for Gordon Bierwagen”. Gordon is a professor of Coatings and Polymeric Materials Department at NDSU recently received ACS Tess Award. The accepted paper demonstrates a new approach to the crosslinking and filling synthetic latex coatings has been developed. Peroxidized monodisperse latex particles have been used as a crosslinker and, simultaneously, as a filler of polymer coatings based on acrylic and styrene-butadiene latexes.
