| 20090022781 | DELIVERY MEANS - A delivery means, for example a dressing, for delivering an antibacterial metal, for example silver, comprises the metal in combination with a hydrophilic polymer. The polymer may be cross-linked by a butylidene polymer to define a gel. In the examples, silver nitrate may be reduced to metallic silver, protected using polyvinylalcohol which is cross-linked to define a gel. | 01-22-2009 |

| 20100234253 | Method for reducing the viscosity of viscous fluids - A viscous fluid, such as heavy crude oil which is too viscous to enable it to be pumped from a flowing phase of a reservoir into and along a pipeline for delivery to a refinery or other storage facility, may be contacted with a formulation to reduce its viscosity. The formulation comprises a polymeric material AA which includes —O— moieties pendent from a polymeric backbone thereof and said material is optionally cross-linked. In one embodiment, the formulation may comprise polyvinyl alcohol. In an alternative embodiment, the formulation may comprise a cross-linked polymeric material, such as cross-linked polyvinyl alcohol. After the viscous composition has been transported to a desired location, it may be separated from the other components. | 09-16-2010 |
| 20110152212 | Aqueous Formulations - A method of preparing an aqueous formulation of an active material and such a formulation per se are described, wherein the active material has a very low solubility in water. The method may involve contacting active material in solid form with an optionally cross-linked water soluble polymer. The water soluble polymer is preferably a polyvinyl polymer with polyvinylalcohol being preferred. The polymer is optionally cross-linked. The method and formulation may be of particular utility in delivery of anti-cancer drugs or drugs via a pulmonary route. | 06-23-2011 |
