摘要： The pH of a wound is assessed using a hydrogel film which changes colour in dependence upon pH. Suitably, the hydrogel film incorporates an indicator, across substantially its entire extent so that the film may be used to monitor pH across a wound. Wound pH information may be used to facilitate selection of the appropriate treatment to which the wound should be subjected. Suitably, the hydrogel film is incorporated into a dressing.

摘要： Water problems in the production of oil or gas from subterranean formations is addressed by providing a method of restricting passage of a fluid from a first location to a second location in a subterranean formation by injecting into the formation a formulation comprising a first material, for example a dialdehyde, arranged to cross-link a second polymeric material, for example a polyvinyl alcohol, thereby to form a polymeric material of high viscosity which may block the passage between the first and second locations.

摘要： A process for recovering materials from a subterranean formation, for example in enhanced oil recovery, comprises: (A) (a) (i) selecting a first polymeric material having a repeat unit of formula (A) wherein A and B are the same or different, are selected from optionally-substituted aromatic and heteroaromatic groups and at least one comprises a relatively polar atom or group and R1 and R2 independently comprise relatively non-polar atoms or groups; or (ii) selecting a first polymeric material prepared or preparable by providing a compound of general formula (B) wherein A, B, R1 and R2 are as described above, in an aqueous solvent and causing the groups C═C in said compound to react with one another to form said first polymeric material; (b) selecting a second polymeric material which includes a functional group which is able to react in the presence of said first polymeric material to form a third polymeric material; (c) causing the formation of said third polymeric material by a reaction involving said first and second polymeric materials; and (d) contacting the subterranean formation with said third polymeric material; or (B) contacting the formation with a polymeric material (hereinafter “said third polymer material”) which is a product of a reaction involving: (a) a first polymeric material as described in (A) (a) (i) or (ii); and (b) a second polymeric material which includes a functional group which is able to react in the presence of said first polymeric material to form said third polymeric material.
摘要翻译：（A）（a）（i）选择具有式（A）的重复单元的第一聚合物材料，其中A和B相同，或者不同的，选自任选取代的芳族和杂芳族基团，并且至少一个包含相对极性的原子或基团，并且R 1和R 2独立地包含相对非极性的原子或组; 或（ii）选择通过提供通式（B）的化合物制备或制备的第一聚合物材料，其中A，B，R 1和R 2如上所述在水性溶剂中并使所述化合物中的基团CC彼此反应以形成所述第一聚合物材料; （b）选择第二聚合物材料，其包括能在所述第一聚合物材料存在下反应形成第三聚合物材料的官能团; （c）通过涉及所述第一和第二聚合物材料的反应引起所述第三聚合物材料的形成; 和（d）使所述地层与所述第三聚合物接触; 或（B）使该地层与聚合物材料（以下称为“所述第三聚合物材料”）接触，所述聚合物材料是反应产物，该反应涉及：（a）如（A）（a）（i）或（ ii）; 和（b）第二聚合物材料，其包括能够在所述第一聚合物材料存在下反应以形成所述第三聚合物材料的官能团。
