METHOD FOR RECYCLING RECOVERED POLYCONDENSATION POLYMER |
摘要 |
<p>Disclosed is a method for recycling a recovered polycondensation polymer which comprises a process wherein a recovered polycondensation polymer is supplied in a molten state to a polymerizer having a porous plate, and then after ejecting the polycondensation polymer through pores of the porous plate, the polymerization degree of the polycondensation polymer is increased under a reduced pressure or in a reduced inert gas atmosphere while dropping the polycondensation polymer along a supporting body.</p> |
