  • Publication number: 20230180864
    Abstract: A face mask is disclosed. The face mask includes a mask pad adapted to cover a nose and a mouth of a wearer and allows a passage of air therethrough to the wearer and restricts a passage of microbes. The mask pad has at least a surface protected by a sulfonated polymeric layer for killing at least 90% microbes within 120 minutes of contact with at least a surface of the face mask. The sulfonated polymeric layer consists essentially of a sulfonated polymer, the sulfonated polymer being selected from the group of perfluorosulfonic acid polymers, polystyrene sulfonates, sulfonated block copolymers, sulfonated polyolefins, sulfonated polyimides, sulfonated polyamides, sulfonated polyesters, sulfonated polysulfones, sulfonated polyketones, sulfonated poly(arylene ether), and mixtures thereof.

  • Publication number: 20230174793
    Abstract: A frequently-touched surface for use by multiple users includes a surface protected by a laminate structure. The laminate structure includes a self-sterilizing sulfonated polymeric outer layer, sulfonated to a certain % to kill at least 95% microbes within 30 minutes of contact. The self-sterilizing sulfonated polymer layer can be applied to the frequently touched surface by any of coating, lamination, and spraying. The sulfonated polymer in embodiment is selected from perfluorosulfonic acid polymers, polystyrene sulfonates, sulfonated block copolymers, sulfonated polyolefins, sulfonated polyimides, sulfonated polyamides, sulfonated polyesters, sulfonated polysulfones, sulfonated polyketones, sulfonated poly(arylene ether), and mixtures thereof. The sulfonated polymer has a degree of sulfonation of at least 10%.

  • Publication number: 20230167343
    Abstract: The disclosure relates to laminate structures to cover or protect substrates or surfaces. The laminate structure comprises a support layer and a self-sterilizing/antimicrobial layer comprising a sulfonated polymer, capable of killing microbes within minutes and for an extended period of time. The sulfonated polymer has a sufficient degree of sulfonation to kill in less than 120 minutes at least 90% of microbes in contact with the surfaces, and for extended protection of the surfaces for at least one month. The laminate structure is particularly suitable for protecting high-touch surfaces such as door knobs, touch-screens, tables, as well as for use with facemasks, face shields, or as self-sterilizing wraps for surgical instruments and supplies. The laminates can also be used as garments or to cover/protect personnel having contagious diseases, etc., to decrease the transmission of microbes.

  • Publication number: 20050256265
    Abstract: The present invention relates to articles prepared from novel anionic block copolymers of mono vinyl aromatics and conjugated dienes, and to blends of such block copolymers with other polymers. The block copolymer may be blended with at least one other polymer selected from the group consisting of olefin polymers, styrene polymers, amorphous resins and engineering thermoplastic resins.
