After solution polymerization, the polymer needs to be purified and dried
into powdered form. Purification is easy---just use lots of water to extract
. How about the drying process? How to make the polymer powdery in the end (
the polymer is glassy at room temperature)? I am not sure how the chemical
industry handles that. Thanks for your suggestion.

I think, for the irregular particles --- use mechanical grinding;
for the regular particles --- use suspension or emulsion
polymerisaion; dispersion or precipitation polymerisation.
