  • Patent number: 11071485
    Abstract: The present invention provides a bio-electrode composition including a polymer compound having both an ionic repeating unit A and a (meth)acrylate repeating unit B, wherein the ionic repeating unit A is a repeating unit selected from the group consisting of sodium salt, potassium salt, and ammonium salt having either or both partial structures shown by the following general formulae (1-1) and (1-2), and the (meth)acrylate repeating unit B is a repeating unit shown by the following general formula (2).

  • Patent number: 11046605
    Abstract: Random copolymers from itaconic acid and/or isomers and sodium alkenyl sulfonates are obtained by polymerization in an aqueous solution via free radicals at an acidic pH in the range from 1.0 to 3.5 and with a redox system as initiator were described. The copolymers can be used as calcium carbonate and calcium, strontium and barium sulfates mineral scale inhibitors and as dispersants of clays, iron oxides, calcium carbonate and strontium, barium and calcium sulfates. Random copolymers prevent and control damage in an oil reservoir, obstruction of water injection and crude oil production pipelines, and in production rigs due to mineral scale precipitation caused by high levels of salinity of the injection water and formation water. Random copolymers are tolerant to high concentrations of divalent ions, such as calcium, magnesium, strontium and barium, and can be added to the reservoir and to injection or production pipelines, treated water, sea water and water that is used as means of transportation.
