Abstract

С метода се улеснява и ускорява получаването на високоустойчив гел. Използва се воден разтвор на поливинилов алкохол със степен на хидролиза > 98 mol%. Прибавя се добавка, която се разтваря във водния разтвор на поливиниловия алкохол и при увеличаване на концентрацията образува отделена, финодиспергирана, съдържаща вода фаза. Водният разтвор се изсушава до остатъчно съдържание на вода до 50 тегл.% за получаване на фазоотделянето и на свързаното с него желиране на поливиниловия алкохол. Набъбването на поливиниловия алкохол се възстановява във водниста среда.
