ABSTRACT:
A process is provided for preparing particles of polymer by heating the polymer having an inherent viscosity not exceeding about 0.6 dl/g when measured at a temperature of about 30.degree. C. in chloroform or hexafluoroisopropanol, dividing the heated polymer into particles, and then solidifying these particles such that substantially no fibers are formed among the particles.
