I need to convert my polymeric compound which is very thick and sticky semi-solid into a very fine solid material. Is there any way to do apart from applying stress on the material.
Please suggest some other techniques available (If Any).
Try to freeze your polymeric compound with liquid nitrogen, and then powder it while it is cold, and see if you can retain the powdered form again, when brought back to room temperature. In case it again retains its sticky semi solid form, then one has to think of some other technique.

Do you want dry powder? If that is the case then you can try lypholizing (dry freezing) the compound.
Thank You Professor Sreenivas for your valuable answer. I would try the same and try to get positive results.
Hi Apoorva,
Getting a dry powder is another task. The polymeric material is practically insoluble in water so first I am sure that my compound is dry already. Just I need a technique to powder it from the thick semi-solid form.
I recommend the following steps:
1-First by melting the polymeric compound,
2-Then by dry freezing the molten polymeric compound
or by freezing the polymetric compound in insoluble solution ,i.e., water.
3-Eventually by sieving the polymeric powder.
4-Finally by drying the sieved powder in a suitable desiccator.
Hi there! Could you elaborate more on why you want to do this? This might help in finding the correct approach.
