    Abstract: A nonwoven web and method of preparing a novel nonwoven web of superabsorbent fiber are disclosed. An aqueous solution of superabsorbent precursor polymer is extruded under defined conditions through a plurality of die orifices to form a plurality of threadlines. The threadlines are attenuated with a defined primary gaseous source to form fiber under conditions of controlled macro scale turbulence and under conditions sufficient to permit the viscosity of each threadline, as it leaves a die orifice and for a distance of no more than about 8 cm, to increase incrementally with increasing distance from the die, while substantially maintaining uniformity of viscosity in the radial direction, at a rate sufficient to provide fiber having the desired attenuation and mean fiber diameter without significant fiber breakage. The attenuated threadlines are dried with a defined secondary gaseous source. The resulting fibers are deposited randomly on a moving foraminous surface to form a substantially uniform web. Moving foraminous surface is positioned about 10 to about 100 cm from the last gaseous source to contact the threadlines. The fibers have a mean fiber diameter in the range of about 0.1 to 30 mu m and are substantially free of shot. The attenuating and drying steps are carried out under conditions of controlled macro scale turbulence.

    Abstract: Fibre or film of water-absorbent water-insoluble fibrous material has a matrix of a cross-linked copolymer formed from 50 to 95 % by weight of ethylenically unsaturated carboxylic monomer and 5 to 50 % by weight of copolymerisable ethylenically unsaturated monomer. The matrix contains regions of a dispersed polymeric material, the matrix copolymer and the dispersed polymeric material being mutually immiscible and chemically substantially non-reactive under ambient conditions. The fibre or film can be produced by extruding a solution or dispersion of the polymeric material in a solution of the matrix copolymer in its non-cross-linked state into a gaseous environment.

    Abstract: A fibrous properties-switching article comprises a mat consisting of fibers having a fiber diameter of 2 microns or less. The fibers comprise a polymer, copolymer, polymer blend, or polymer network, wherein the fibers have a diameter of 2 μιη or less. The surface and/or bulk property of the mat changes over a range of temperatures, wherein the polymer, copolymer, polymer blend, or polymer network undergoes a structural change over the range of temperatures. The fiber mat is formed by electrospinning. In an exemplary embodiment, a blend of polystyrene and poly((N-isopropyl acrylamide) (bl-PS/PNIPA) in dimethylformamide (DMF) is electrospun to form a mat consisting of fibers with a diameter less than 2 μηι that shows a transition from a superhydrophilic surface to a nearly superhydrophobic surface over a temperature range from 30 °C to 45 °C. A fiber mat formed by electrospinning a DMF solution comprising poly(N-isopropyl acrylamide-co- methacylicacid) (PNIPAMAA), comprises fibers having a diameter less than 2 μιτι and are cross linked after spinning. The crosslinked PNIPAMAA, (xl-PNIPAMAA) fiber mat displays a transition from a hydrophilic surface to a nearly hydrophobic surface over a temperature range from 30 °C to 45 °C.

    Abstract: A supramolecular polymer with living characteristics is provided based on small molecules or metal complexes of a planar or linear geometry and a polymer. The small molecules are solvophobic and can associate or assemble with each other through non-covalent interactions such as but not limited to metal–metal, π–π, hydrogen-bonding, and/or solvophobic–solvophobic interactions, in the modulation of the polymer. The polymer has affinity to the medium (e.g., solvent) and still interacts with the small molecules via non-covalent interactions such as electrostatic attractions to stabilize the associated/assembled small molecules. Varying the composition and/or length of the polymer can modulate the dimensions of the supramolecular polymer and the nanostructures therefrom. The two-or multi-component supramolecular polymer has active ends to support further supramolecular polymerization upon addition of small molecules of a planar or linear geometry. A process of two-component living supramolecular polymerization is also provided.
