| titleOfInvention | Process for preparing carboxyl cation exchanger 1 |
| abstract | The invention relates to a process for preparing high molecular weight substances, more precisely to preparationnsynthetic ion exchangers - a weakly acidic polymeric cation exchanger.nThe Soviet Author's Certificate No. 322332 describes a method for preparing a porous carbonxyl cation exchanger for the separation of proteins and enzymes from physiological solutions.nThis cation exchanger is obtained by copolymerizing methacrylic acid with 4 to 8 moles. % hexa-nhydro-1,3,5-triacryloyltriazine in dilute aqueous solutions (5 to 30 vol%) of acidn% acetic acid, at a monomer concentration of 20 to 25 wt. in the presence of a redox system at heatn20 to 100 ° C.nThis known cation exchanger has no functional groups other than carboxyl groups in its structure,nwhich narrows the area of its use.nIt is an object of the present invention to provide a carboxyl cation exchange resin which can be used tonenzymes.nThe principle of the process for producing carboxyl cation exchange by crosslinking polymerization in dilute solutionnacetic acid in the presence of a redox system, according to the present invention,nthat copolymerizes methacrylic acid and 2-hydroxypropyl methacrylamide in a ratio ofn9 · 0.1 to 1 and up to 20 mol with the crosslinker. % at 20 to 100 ° C. |
