  • Patent number: 7534376
    Abstract: The invention provides a conductivity control agent comprised of a polymeric material containing diphosphonium bis(sulfoarylcarbonyloxy) glycol salts as conductivity control agent. The conductivity control agents can be used with semi-conductive rolls, belts and other biasable members. The inclusion of the conductivity control agent in the polymeric or polyurethane elastomers extends the electrical life of the polymeric biasable member in low humidity environments. Additionally, the resistivity of the elastomeric polymer on the biasable member is controlled to a desirable value by adjusting the conductivity control agent level in the elastomers.

  • Patent number: 7462679
    Abstract: Glycerides of acids having conjugated groups of aliphatic carbon-carbon double bonds, such as tung oil, are functionalized by reaction with certain polyol compounds at mild conditions. The functionalized oils are useful in a variety of coating and adhesive applications. They can be cured with melamine-formaldehyde, urea-formaldehyde, benzoguanimine-formaldehyde and/or glycoluril-formaldehyde resins. They can be reacted with polyisocyanates to form polyurethanes, and urethane-group containing prepolymers. Of particular interest are water-dispersible prepolymers, which can be used to make anionic, cationic or nonionic polyurethane dispersions for coating, adhesive and sealant as well as composites applications.

  • Patent number: 7439316
    Abstract: A process for the preparation of stable aqueous polycarbodiimide dispersions, to be used as crosslinking agent, which are free of organic solvents is described. Sid process is characterized in: reacting a polyisocyanate in the presence of a carbodiimide catalyst to form a polycarbodiimide, terminating and/or chain extending the polycarbodiimide chain by the addition of formation dispersion of the resulting compound in water, wherein pH is adjusted to a value between 9 and 14 by the addition of a base and/or a buffer to the water used for the dispersion and/or to the obtained aqueous dispersion. According to the present process said terminating or chain extending with the compound containing a hydrophylic group and one or more amine functions may also occur during or after the dispersion of the polycarboiimide in water. The preferred pH of the polycarbodiimide dispersions is between 11 and 13.

  • Patent number: 7345117
    Abstract: The present invention relates to the synthesis of a haemocompatible polymer, consisting of a polyurethane bound covalently to sulphated hyaluronic acid. These sulfated derivatives have anticoagulative, non-thrombogenic, antiviral and anti-inflammatory properties. They also have the ability to inhibit platelet adhesion, aggregation and activation. The invention is particularly advantageous in resisting the enzyme hyaluronidase, therefore ensuring anti-coagulant activities for longer periods of time when compared to similar compounds. This biocompatible polymer material is well suited for surgical or other medicinal uses.
