| titleOfInvention | A method of preparing sorbents with carboxyl functions |
| abstract | The invention relates to a process for preparing sorbentsnbased on copolymers with carboxyl functionsnand having permeable or gelnporosity.nThe object of the present invention is a methodnpreparation of sorbents with carboxyl groups,nwhich consists in hydrolyzing themncopolymers of the monomer selected fromnincluding alkyl (meth) acrylates, hydroxyalkyl (meth) acrylatesnand (polyhydroxy) alkyl (meth) acrylates,nwherein alkyl has 1 to 4 atomsn% carbon with 2 to 40 wt. %, based onnmonomer mixture (ethylenedi (meth) acrylate).nThe hydrolysis according to the invention is carried out in alkaline formn20 to 50 wt. waternsolution or aqueous-organic hydroxidensodium (NaOH), being organicnthe component is ethylene glycol monoethyl ether.nThe benefit of ion exchangers prepared according to the proposednthe fast kineticsnion exchange due to preferencenexchange groups into surface layersnpolymer by using subsequent chemical conversion,nFurthermore, limited water retention, smallnchanges in retention cycles, goodnmechanical resistance and the fact that znone type of copolymer can be prepared in its entiretyna variety of different networking, which is easiernthan by copolymerization. |
