ABSTRACT:
Disclosed is a process for reducing the self-adhesiveness of polytrimethylene terephthalate pellets, which can be carried out in a continuous or batch manner comprising the steps of:a) introducing polytrimethylene terephthalate pellets having an intrinsic viscosity of at least about 0.4 dl/g into a conduit containing a liquid which is moving through the conduit, thereby causing the pellets to move through the conduit with the liquid;b) adjusting the temperature of the pellets and the liquid to a temperature of about 50 to about 95° C. for a time sufficient to induce a degree of crystallinity of at least about 35% in the pellets; andc) separating the pellets from the liquid.
