Abstract
Procedeu de obtinere a schimbatorilor de ioni selectivi pentru bor prin clormetilarea, în mod cunoscut, a unui copolimer reticulat stirendivinilbenzen-acrilonitril cu greutate moleculara cuprinsa între 30000 si 90000 cu 2 si 8% si acrilonitrilul cuprins între 1 si 10% obtinut în prezenta polistirenului ca mediu inert în cantitate de 10...30% fata de amestecul total de monomeri, copolimerul astfel clormetilat umflat în prealabil în dimetilformamida-apa, se amineaza cu o solutie de N-metil-glucamina de 20...35% în dimetilformamida sau în amestec de dimetilformamida-apa în proportie de 1/3....2/3 la temperatura de 80...95 degree C.
