Abstract
Process for thermal solid-state treatment of chips of saturated polyester, where the chips are crystallized immediately before the thermal treatment and the thermal treatment is carried out in a static bed at a chip temperature that is equal to TE (1 .mu.m) .+-.2.degree. C., where TE (1 .mu.m) is the temperature at which a measurement probe placed on a crystallized chip is lowered by 1 .mu.m under defined conditions in a thermomechanical analysis. The crystallization preferably takes place in a fluidized bed at three different specified temperatures.
