Abstract: The present disclosure generally relates to microemulsion compositions that include an active ingredient and exhibit high clarity. The microemulsion compositions may be substantially bio-based, partially bio-based or non-bio-based and exhibit a lightness value and transmittance equal to or higher than commercially available non-bio-based microemulsion compositions. The microemulsion compositions provided herein are efficient to manufacture and maintain high clarity when subjected to high temperatures for long periods of time, freeze-thaw cycles, as well as intermediate temperatures. The microemulsion compositions provided herein produce near-universal stability with a variety of active ingredients such as oils or fragrances, thus reducing inventory costs for storage of emulsion surfactants.

Abstract: An aqueous ink jet ink is made by forming a mixture of a pigment, an optional dispersant if the pigment is not self-dispersing, dispersing, and a urethane polymer or prepolymer dispersion in water. This ink is useful in a variety of ink jet printing applications such as printing on wide format substrates and textiles.

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.

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.

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.

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.

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.
