| titleOfInvention | Porous hydrophilic ion exchangers containing exclusively quaternary ammonium groups and a process for their preparation |
| abstract | Porous hydrophilic ion exchangers containing exclusivelynquaternary ammonium groups covalently boundnthe carbon oxirane group of carriersnare copolymers or epoxidized copolymersnhydroxy esters or glycidyl estersnacrylic or methacrylic with crosslinkingnmonomers containing two ornmultiple double bonds capable of copolymerization. The quaternary ammonium groups of these carriers haventhe formula R-N ± (CH 3) 2, wherein R may be mononpolyhydroxyalkyl having 2 to 6 carbon atomsnor alkynyl of 3 to 6 carbon atoms ornC 3 -C 6 alkanonyl or alkylene carboxylatenwith 4 to 8 carbon atoms ornan aldehyde diacetal radical having 4 to 8 atomsncarbon. Ionexes according to the invention are preparednby reacting the above carrier with tertiarynan amine of the formula R-N- (CH 3) 2, wherein R 6nhas the above meaning. |
