Abstract

Procedeul de preparare a copolimerilor macroporosi consta în faptul ca se supune reactiei de polimerizare stirenul sau esteri acrilici sau metacrilici sau acrilonitrilul în procent de 30...95%, cu divinilbenzenul în procent de 50....70% în prezenta unui extractant organic ales dintre acid capronic, acetofenona, metilzobutilcetona în procent de 10...60% fata de monomeri, la temperatura de 60....80 degree C dupa care copolimerul astfel obtinut poate fi utilizat ca atare drept mediu inert pentru obtinerea altor copolimeri sau se poate transforma în schimbatori de ioni ce extractul s-a îndepartat.
