METHOD FOR PRODUCING CRYSTALLIZED POLYESTER

摘要

A METHOD FOR PRODUCING A CRYSTALLIZED POLYESTER COMPRISES THE CRYSTALLIZATION STEP OF APPLYING A SHEAR AND/OR A PRESSURE TO A POLYESTER SELECTED FROM AN ALIPHATIC POLYESTER AND A POLYALKYLENE TEREPHTHALATE AT A TEMPERATURE OF (TM-70°C.) TO (TM+20°C.), WHERE TM IS A MELTING POINT OF THE POLYESTER, THEREBY CONVERTING THE POLYESTER INTO A STATE HAVING A CRYSTALLINITY OF 10% OR MORE AND FLUIDITY.
