• An injection water viscosifier for enhanced oil recovery

  公开号：EP0094898A2

  公开（公告）日：1983-11-23

  High molecular weight N,N-dimethylacrylamide copolymers and terpolymers were synthesized. These polymers offer outstanding advantages as injection water viscosifiers in enhanced oil recovery processes including chemical, miscible, and steam or in processes requiring profile improvement through adsorption and/or gelation. They are very valuable in applications where high salinity is a problem since they are relatively insensitive to metal salts (such as those containing polyvalent ions, such as Ca++ and Mg++).

  公开（公告）日：1987-04-01

  Super-absorbent covalently crosslinked copolymers are prepared by reacting a homopolymer of acrylamido hydrocarbon sulfonic acid or an amine salt or a monomer precursor thereof with an allylic crosslinking agent. These copolymers are compatible with a wide variety of materials and can be used wherever superior aqueous fluid absorption and retention is required. Typical applications for these copolymers are in absorbent softgoods and in agricultural areas.

  A biomedical electrode (10) adapted to be applied to a body, the biomedical electrode (10) having a surface area divided into a first zone (38), a second zone (40), and third zone (42). The biomedical electrode (10) has a first layer of adhesive (24) which is electrically conductive and which is adapted to be applied to the body, a conductive layer (22) positioned adjacent the first layer of adhesive (24), a second layer of adhesive (16), and a protective, electrically insulative web (12) positoned adjacent the second layer of adhesive (16). The second layer of adhesive (16) holds the protective, electrically insulative web (12) to the conductive layer (22) in the third zone (42) of the biomedical electrode (10). A removable release liner (18) is positioned in the first zone (38) between the second layer of adhesive (16) and the conductive layer (22) preventing the protective, electrically insulative web (12) from sticking to the conductive layer (22) in the first zone (38) of the biomedical electrode (10). An insertable electrical lead wire (14) is insertable in the first zone (38) between the second layer of adhesive (16) and the conductive layer (22) upon removal of the removable liner (18). The protective, electrically insulative web (12) has an edge (44) in the second zone (40) which is easily grasped so that the protective, electrically insulative web (12) may be pulled and removed from the biomedical electrode (10) allowing removal of the electrical lead wire (14).

  一种适用于人体的生物医学电极（10），生物医学电极（10）的表面区域分为第一区（38）、第二区（40）和第三区（42）。生物医学电极（10）具有导电的第一层粘合剂（24），该粘合剂适用于人体，导电层（22）位于第一层粘合剂（24）的邻近位置，第二层粘合剂（16）和保护性电绝缘网（12）位于第二层粘合剂（16）的邻近位置。第二层粘合剂（16）将保护性电绝缘网（12）固定在生物医学电极（10）第三区（42）的导电层（22）上。第二层粘合剂 (16) 和导电层 (22) 之间的第一区 (38) 内有一个可拆卸的脱模衬垫 (18)，可防止保护性电绝缘网 (12) 粘在生物医学电极 (10) 第一区 (38) 的导电层 (22) 上。移除可拆卸衬垫 (18) 后，可将可插入导线 (14) 插入第一区 (38) 的第二层粘合剂 (16) 和导电层 (22) 之间。保护性电绝缘网（12）在第二区（40）有一个边缘（44），很容易抓住，这样就可以将保护性电绝缘网（12）拉出并从生物医学电极（10）上取下，从而取下引出线（14）。
