Process for preparing polymer particles |
摘要 |
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 DEG 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.
