Claims (6)

1. Способ гранулирования термопластичных полиолефинов, при котором полученный в полимеризационном реакторе полимерный порошок расплавляют и гомогенизируют в экструдере, затем продавливают через экструзионное сопло и гранулируют, причем перед загрузкой в экструдер полимерный порошок подвергают термообработке, отличающийся тем, что загрузку полимерного порошка в экструдер осуществляют при температуре порошка в диапазоне 5-30 К ниже температуры плавления полимера, при этом необходимую для термообработки полимерного порошка тепловую энергию получают за счет дешевого отходящего тепла, имеющегося в распоряжении на производственных территориях.
2. Способ по п.1, отличающийся тем, что термообработку осуществляют таким образом, что температура полимерного порошка возрастает до значения в диапазоне 10-20 К ниже температуры плавления полимера.
3. Способ по п.1 или 2, отличающийся тем, что перед загрузкой в экструдер полимерный порошок нагревают водяным паром, а затем сушат горячим воздухом или горячим азотом.
4. Способ по одному из п.1 или 2, отличающийся тем, что перед загрузкой в экструдер полимерный порошок пропускают через нагретую снаружи трубу.
5. Способ по одному из п.1 или 2, отличающийся тем, что перед загрузкой в экструдер полимерный порошок нагревают в теплообменнике для сыпучих материалов, причем массовый поток регулируют посредством вибротранспортера, и полимерный порошок проходит через нагретые металлические плиты.
6. Способ по одному из пп.1-5, отличающийся тем, что его применяют для гранулирования полиэтилена или полипропилена.
