Abstract
Изобретение касается синтезу высокомолекулярных соединения, в частности иономерных водорастворимых полиуретанов, которые получают из изоцианатов и которые могут найти применение в качестве полифункциональных материалов в разных отраслях народного хозяйства. Сущность изобретения: иономерные водорастворимые полиуретаны получают путем взаимодействия полиэфиров и диизоцианатов с образованием форполимера и его продолжением соединениями, содержащими третичный атом азота с последующим приданием ионной формы полиуретану за счет солеобразования. Новым является то, что в качестве соединений, содержащих третичный атом азота, используют 1,1-диметилгидразин или компонент жидкого ракетного топлива "Гептил" и добавляют их в форполимер из расчета 0,66-0,75 моль последних на 1 моль полиэфира. Технический результат: придание полиуретанам водорастворимости.
