Aiming at the preparation of nanometer-size polydiacetyline microcrystals, the crystallization process during reprecipitaiton method was investigated using electron micrographs and light-scattering technique. We found that an amorphous nanoparticle was formed initially and subsequently crystallized. We conclude that amorphous nanoparticles must be sufficiently small in order to achieve nanometer-size crystals.
