  • Patent number: 8901232
    Abstract: This invention relates to aqueous polyurethane compositions suitable for dipped surgeon's gloves and related articles needing toughness, pliability, and some solvent resistance. The gloves replace natural latex gloves which can cause allergic reactions and/or isoprene gloves which have their own drawbacks.

  • Publication number: 20100267299
    Abstract: Vinyl chloride polymer compositions, optionally plasticized, containing a hydrophilic polymer (e.g., a hydrophilic polyurethane or hydrophilic vinyl polymer) are described for use as coatings and films with increased moisture vapor transmission and/or static dissipative properties. Films from this material are useful as fluid barriers that allow diffusion of moisture vapors. Similar modifications can be made to acrylate and urethane polymers.

  • Patent number: 6897281
    Abstract: A breathable polyurethane having an upright moisture vapor transmission rate (MVTR) of more than about 500 gms/m2/24 hr comprises: (a) poly(alkylene oxide) side-chain units in an amount comprising about 12 wt. % to about 80 wt. % of said polyurethane, wherein (i) alkylene oxide groups in said poly(alkylene oxide) side-chain units have from 2 to 10 carbon atoms and are unsubstituted, substituted, or both unsubstituted and substituted, (ii) at least about 50 wt. % of said alkylene oxide groups are ethylene oxide, and (iii) said amount of said side-chain units is (i) at least about 30 wt. % when the molecular weight of said side-chain units is less than about 600 grams/mole, (ii) at least about 15 wt. % when the molecular weight of said side-chain units is from about 600 to about 1,000 grams/mole, and at least about 12 wt. % when the molecular weight of said side-chain units is more than about 1,000 grams/mole, and (b) poly(ethylene oxide) main-chain units in an amount comprising less than about 25 wt.

  • Patent number: 6576702
    Abstract: Waterborne polyurethane dispersions are prepared by reacting (1) at least one polyisocyanate; (2) at least one active hydrogen containing compound, such as a polyol or a polyamide; and (3) preferably also at least one water-dispersability enhancing compound having water-dispersion enhancing groups, in order to form an isocyanate terminated prepolymer. The prepolymer subsequently is (1) optionally neutralized by reaction with at least one neutralizing agent, (2) dispersed in water, and then (3) chain extended by reaction with at least one of water, inorganic or organic polyamine having an average of about 2 or more primary and/or secondary amine groups, or combinations thereof. At least one plasticizer is introduced into the reaction mixture at any time during prepolymer formation or before the prepolymer is dispersed in water. The plasitcizer substantially or completely replaces other organic diluents or solvents. Various types of plasticizers may be employed, including reactive plasticizers.

  • Patent number: 6017997
    Abstract: A waterborne dispersion of a polyurethane polymer is disclosed, which is useful as a film having improved mechanical properties. More particularly, the film has properties comparable to rubber; including, a percentage elongation greater than 700%; a tensile strength greater than 3500 psi; a 100% modulus below 450 psi; a 300% modulus below 700 psi; and, a 500% modulus below 1500 psi. The film can be prepared in the absence of a solvent, thus making it attractive for a variety of protection products for medical and industrial applications such as gloves, condoms, catheters, and the like. The polymer is useful as a coating for textiles, such as backcoatings, fabric or fiber saturants, finishes, or transfer coatings, or other textile and non-textile applications where good elastomeric properties would be useful.
