Abstract

Способ кристаллизации совокупности гранул кристаллизующегося полимера включает этап, на котором гранулы контактируют в кристаллизаторе с текучей средой-регулятором температуры. Среда регулирует температуру гранул, имея достаточную температуру, чтобы позволить, по крайней мере, частичную кристаллизацию совокупности полимерных гранул, поддерживая при этом среднюю температуру совокупности гранул ниже температуры плавления гранул. Заявлен также кристаллизатор, осуществляющий способы изобретения.
