NOVELTY - A thermoset ionomer contains crosslinked network of polymer chains which are covalently bonded to one another by pendant cationic moieties. The cationic moieties comprise bis-N-alkylated azolium ion, N-alkylated azolium ions, or P-alkylated phosphonium ions.    USE - Thermoset ionomer is used for kit used for article (claimed) e.g. fuel cell membrane, pharmaceutical stopper, syringe fitting, ion-exchange resin, separation membrane, bathroom safety equipment, garden equipment, spa equipment, water filtration equipment, sealant, grout, contact cement, adhesive, pressure-sensitive adhesive, tank liner, membrane, packaging material, cell-culture equipment, light switch, exercise equipment, railing, sports equipment, steering wheel, writing tool, luggage, o-ring, tire inner liner, tire tread, thermoplastic vulcanizate, gasket, appliance, baby product, bottle, lid, toilet seat, bathroom fixture, flooring, surface, surface for food preparation, utensil, handle, grip, doorknob, container for food storage, gardening tool, kitchen fixture, kitchen product, office product, pet product, water storage equipment, food preparation equipment, shopping cart, surfacing material, storage container including food storage container, footwear, protective wear, sporting gear, cart, dental equipment, door knob, clothing, handheld device, telephone, toy, container for fluid, catheter, keyboard, surface of vessel, surface of pipe, surface of duct, coating, food processing equipment, materials handling equipment, auger, conveyor belt, biomedical device, filter, additive, computer, dock, drilling platform, ship hull, underwater infrastructure, heating, ventilation and air conditioning equipment, shower wall, shower flooring, implant, medicinal textile material, tissue sealant, tissue adhesive, personal protective equipment, wetsuit, drysuit, respiratory mask, article to minimize biofouling, pacemaker, wound dressing, ice machine, water cooler, fruit juice dispenser, soft drink machine, piping, storage vessel, metering system, valve, fitting, attachment, filter housing, lining, barrier coating, insulation, chemical protective equipment, and biochemical protective equipment (all claimed).    ADVANTAGE - The ionomer, kit or article has excellent adhesiveness with respect to glass, plastic, mineral, metal and ceramics, and reduces accumulation of microorganisms bacteria (Gram-negative and Gram-positive bacteria), algae, fungi, mollusks and arthropods.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) manufacture of thermoset ionomer, which involves reacting halogenated polymer and crosslinking nucleophile;    (2) kit; and    (3) article.
