Abstract

Изобретение касается способа и устройства для получения сферических частиц из расплава полимера, причем расплав посредством капельного сопла (10) выдается покапельно и капли после прохождения зоны осаждения прежде всего, по меньшей мере частично, закристаллизовываются и затем подаются на стадию кристаллизации с целью перекристаллизации и после этого на стадию последующей конденсации для твердофазной поликонденсации. Чтобы предотвратить при частичной кристаллизации опасность слипания частиц как друг с другом, так и с частями установки, предлагается, чтобы капли оседали на стадии кристаллизации (45), снабженной тканеподобным или листовым элементом с отверстиями, которые пропускают газ для завихрения капель.Международная заявка была опубликована вместе с отчетом о международном поиске.
