  • Patent number: 10174144
    Abstract: The present invention relates to cationic copolymers, a process for the production of these cationic copolymers and the use of these cationic copolymers as dispersants for geopolymer binder systems. These cationic copolymers where the cationic charge is due to the presence of certain cyclic and/or polycationic groups are stable towards Hoffmann elimination that would otherwise occur at very high pH values. Moreover, the dispersing effect of cationic polymers can be further enhanced through the addition of polyvalent anions.

  • Publication number: 20140319063
    Abstract: A process for obtaining random copolymers from itaconic acid and/or isomers and sodium alkenyl sulfonates is 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. 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.
