Improvement in PET properties via self-nucleation is demonstrated. PET is modified through a precipitation technique, and used as a homogeneous self-nucleant, because, unlike as-received PET, it is rapidly crystallizable from the melt. Thermal, mechanical, permeability, and other relevant properties of self-nucleated PET films and fibers are much improved. Repeated self-nucleation has also been demonstrated, by re-using self-nucleated PET as a nucleant.
