Abstract
Inventia de fata se refera la un procedeu de preparare a unor schimbatori de anioni prin copolimerizarea unui amestec de stirendivinilbenzen-componenta acrilica, în prezenta unui amestec de medii inerte, constituit din polistiren si benzina de extractie cu punct fierbere 110...200 degree C, apoi clormetilarea si aminarea în mod cunoscut. Se obtin schimbatori de anioni cu structura permanent poroasa, cu pori superlargi, destinati retinerii bioxidului de siliciu coloidal.
