Abstract
Inventia se refera la un procedeu de preparare a unui polielectrolit anionic prin reactia de copolimerozare a anhidridei maleice cu acetatul de vinil folosind drept mediu de reactie benzenul, în prezenta peroxidului de benzoil ca initiator, în care îndepartarea benzenului se realizeaza prin adaos de apa în proportie convenabila fata de masa de reactie si distilare azeotropa la 60...90 degree C, la un vid 20....250 mmHg pîna la îndepartarea benzenului si solubilizarea copolimerului obtinut în apa.
