The present invention provides a phosphate adsorbing agent for blood processing comprising a porous formed article comprising an organic polymer resin and an inorganic ion adsorbent and having a most frequent pore size of 0.08 to 0.70 μm measured with a mercury porosimeter, the phosphate adsorbing agent for blood processing having a biocompatible polymer in the surface of the porous formed article.

An anion exchange membrane is made by mixing 2 trifluoroMethyl Ketone [nominal] (1.12 g, 4.53 mmol), 1 Biphenyl (0.70 g, 4.53 mmol), methylene chloride (3.0 mL), trifluoromethanesulfonic acid (TFSA) (3.0 mL) to produce a pre-polymer. The pre-polymer is then functionalized to produce an anion exchange polymer. The pre-polymer may be functionalized with trimethylamine in solution with water. The pre-polymer may be imbibed into a porous scaffold material, such as expanded polytetrafluoroethylene to produce a composite anion exchange membrane.

The present invention is related to a separating agent for the purification of human insulin, ensuring that human insulin can be recovered in high yield when isolating human insulin from a solution containing human insulin and a specific insulin under specific liquid chromatography separation conditions by using the separating agent.

The present invention is a solid lubricant treatment medium, usually but not always in bead form, suitable to be brought into contact with lubricants to remediate and to condition them. A key feature of the medium, typically a polymeric resin, is the presence of relatively very large pores, which are able to capture and remove fine lubricant contaminants and breakdown products (such as small phosphate ester varnish, soot, coke, dissolved metal or other small semi-soluble or insoluble particles), Resins and adsorbents of the prior art have proven unable to remove fine contaminants like phosphate ester varnish that have a deleterious impact on industrial equipment performance and reliability. The mean pore size diameter of the medium is between about 8,000 Å and 100,000 Å and, more preferably, in the range of about 20,000 Å to about

The disclosure relates to a hydrogenated styrene-based multiblock copolymer composition, having selectively quaternized midblock, for forming anion-exchange membranes (AEMs). The quaternized hydrogenated styrene-based multiblock copolymer is characterized as having a high glass transition temperature from the hydrophobic end-blocks, low vinyl (rubber) content, and quaternized mid-block. AEMs made from the composition have improved thermal and dimensional stability in electrolyzer operations.
