摘要:
A process for producing non-solid-stated polyester polymer particles having one or more properties similar to polyester polymer particles that have undergone solid-state processing. In one embodiment, the process comprises (a) forming polyester polymer particles from a polyester polymer melt; (b) quenching at least a portion of the particles, (c) drying at least a portion of the particles, (d) crystallizing at least a portion of the particles, (e) annealing at least a portion of the particles. At all points during and between steps (b) through (e), the average bulk temperature of the particles is maintained above 165° C.
