    • A process is disclosed for forming a synthetic fiber including providing a first component of an aliphatic polyester polymer a second component of a multicarboxylic acid, mixing the first component aliphatic polyester polymer and the second component multicarboxylic acid to form an unreacted specified thermoplastic composition, and melt blending the unreacted specified thermoplastic composition in an extruder or a mixer. The second component multicarboxylic acid lubricates the extruder and provides a nucleating agent for crystallizing the specified thermoplastic composition to form a mean crystal size less than about 120 Angstroms. Fiber composed of the specified thermoplastic composition has a mean crystal size less than about 120 Angstroms. The fiber has a glass transition temperature (Tg) less than about 55.degree. C. In one aspect, a first component of polylactic acid and a second component of adipic acid provide synthetic fibers in a nonwoven structure used in a biodegradable and compostable disposable absorbent product for the absorption and removal of body fluids.

    • A method for preparing polyester films, which comprises addition of partially esterified trimellitate at any stage of the polymerization of polyester through direct esterification or ester interchange, the partially esterified trimellitates resulting from salt formation of partial esterified trimellitic acids which are prepared by partial esterification of aromatic tricarboxylic acids selected from trimellitic acid and trimellitic anhydride with alcohols selected from alkyl alcohols and alkylene alcohols. The polyester film prepared the composition has little voids by virtue of good affinity of the particles originating from the partially esterified trimellitates with polyester and thereby not easily broken when forming films. In addition, it is easy to control particle content and size. Further, fine protrusions can be repeatitively formed in the final films, with ease, giving high abrasion resistance and slip property to the film. Besides, the polyester films can be formed in high casting speed attributable to superior electrostatic adhesion.
