Abstract

Описывается способ непрерывного или прерывного получения эластомерных сополиэстров из полибутиленфталата (ПБТ) и полиокситетраметиленгликоля, причем образующийся при получении из 1,4-бутандиола полибутилентерефталата тетрагидрофуран (ТХФ) превращается после его ректификации путем циклораскрывающейся полимеризации в полиокситетраметиленгликоль, который при помощи свободных или этерифицированных карбоксильных групп ПБТ конденсируют в сополиэстер, причем обрыв цепи и дезактивация катализатора происходят путем добавления 1,4-бутандиола без удаления катализатора.
