D301FC macroporous weakly basic anion exchange resin news report

During the use of resin particles, there are changes such as transfer, friction, expansion, and contraction. After long-term use, there will be a small amount of loss and breakage, so the resin should have high mechanical strength and wear resistance. Generally, resins with low cross-linking are more prone to breakage, but the durability of the resin is mainly determined by the uniformity and strength of the cross-linking structure. Such as macroporous resin, those with high crosslinking degree have stable structure and can withstand repeated regeneration.
This article describes the method of preparing macroporous cation exchange resin. The macroporous cation exchange resin is in the form of particles (such as beads), which contain hydrophilic, cross-linked (methyl) acrylic polymer materials. In addition, the present invention describes a method for purifying positively charged materials using the macroporous cation exchange resin, a method for preparing a chromatographic column comprising the macroporous cation exchange resin, a method for preparing a filter element comprising the macroporous cation exchange resin, and a method for preparing a porous composite material comprising the macroporous cation exchange resin
