Abstract
Inventia se refera la un procedeu de obtinere a unor polimeri solubili anionici stiren anhidrida maleica în care se supune reactiei stirenul cu anhidrida maleica la temperatura de 70.....80 degree C în mediul de benzen si în prezentî de peroxid de benzoil, dupa care copolimerul format se mentine la temperatura de 80 degree C timp de 4h,apoi la temperatura de 70 degree C se adauga apa, benzenul îndepartîndu-se sub forme de azeotropiar la temperatura de 45....500 degree C se introduce solutia de NH4OH sau NaOH catre reactioneaza cu copolimerul dupa care temperatura se ridica la 65...70 degree C cînd procesul se considera terminat.
