A copolymer includes a hydrophobic head segment and a random copolymer tail segment comprising hydrophobic blocks and ionizable blocks. Emulsion polymerization systems incorporate the copolymer as a surfactant.

Hydrophobic block&#x2014;random block copolymer emulsion polymer stabilizers

The present application provides switchable, homogeneous paint composition and methods of painting and/or forming films or coatings using the composition. The composition includes a liquid having an aqueous solution and dissolved acid gas (e.g., carbonated water), and a switchable polymer. The switchable polymer converts from a protonated, water-soluble form in the liquid to a water-insoluble unprotonated form following removal or substantial removal of the liquid and acid gas.

Switchable water-based paint or coating compositions

The present application provides a composite material that comprises a solid and solid-supported non-polymeric switchable moiety, wherein the switchable moiety comprises a functional group that is switchable between a first form and a second form, said first form being neutral and hydrophobic, and said second form being ionized and hydrophilic. The composite material converts to, or is maintained in, said second form when the switchable moiety is exposed to COat amounts sufficient to maintain the ionized form. The composite material converts to, or is maintained in, said first form when COis removed or reduced to an amount insufficient to maintain the ionized form. COis removed or reduced by exposing the composite material to heat and/or a flushing inert gas such as N, Ar, or air. Envisioned uses of these composite materials includes removing water from non-aqueous solvents, removing water vapor from gaseous mixtures, and cleaning industrial reaction vessels and/or pipelines.
