Provided are thermoplastic polymer particles having an aspect ratio of 1.00 or more and less than 1.05, and a roundness of 0.95 to 1.00. The thermoplastic polymer particles are formed from a thermoplastic polymer resin in a continuous matrix phase. The thermoplastic polymer particles show a peak cold crystallization temperature (T.sub.cc) at a temperature between a glass transition temperature (T.sub.g) and the melting point (T.sub.m) in a differential scanning calorimetry (DSC) curve which is derived from temperature rise analysis at 10° C./min by differential scanning calorimetry.

The present disclosure relates to a process for preparing granules from an input material or a powder material. The process comprises feeding the input material for granulation in the processor using one or more powder feeders, introducing steam as a granulation activating agent in the processor, granulating the input material in presence of the steam to form granules, and optionally collecting the granules from a discharge zone of the processor, wherein feed rate of the steam into the processor is determined based on feed rate of the input material into the processor. A co-rotating twin-screw processor for preparing granules is also disclosed.
