Abstract

Изобретение относится к способу получения полимеров поликонденсацией в фазе расплава по меньшей мере на одной реакционной стадии под вакуумом. Образующиеся пары отводят со стадии реакции посредством по меньшей мере одного пароструйного вакуумного насоса с подключенным после него струйным конденсатором. С целью усовершенствования способа пароструйный вакуумный насос приводят в действие алкиленкарбонатом в виде пара, а жидкий алкиленкарбонат подают в качестве охлаждающего агента в струйный конденсатор.
