POLYESTER COMPOSITION, PROCESS FOR PREPARING SAME, AND FILM FORMED USING SAME |
摘要 |
<p>According to the present invention there is provided a polyester composition comprising an aromatic polyester having copolymerized therein a compound containing at least one sulfonic acid group or sulfonic acid metal salt group, and crosslinked polymer particles, preferably crosslinked polymer particles coated with a water-soluble polymer. The particles are incorporated in a slurried state into the polymer. There is also provided a laminate film containing the polymer with the particles thus incorporated therein. The polyester composition is superior in uniform dispersibility of the particles, re-agglomeratin does not occur in melt-storage for a long time, and films formed using the polyester composition are superior in traveling performance and abrasion resistance.</p> |
