ABSTRACT:
Colloidally dispersible microcrystalline polyesters are prepared by a hydrolytic removal of amorphous regions in synthetic, linear polyesters followed by a mechanical disintegration of the resulting aggregated microcrystals to produce discrete microcrystalline particles at least 5% by weight having a particle size not exceeding 1 micron. The microcrystalline polyesters exhibit a sharp X-ray diffraction pattern and distinctly modified thermal behavior as compared to the parent or precursor polyester resin.
