Process for making polyester/platelet particle compositions displaying improved dispersion |
摘要 |
The present invention relates to polyester-platelet particle composite comprising; at least one polyester having dispersed therein a platelet particle dispersion comprising about 0.01 to about 25 weight percent platelet particles and at least one water dissipatible polymer in a concentration which is at least about 1 part water dissipatible polymer to 1 part said polyester wherein said platelet particles primarily comprise individual platelet particles and tactoids. The composites of the present invention are prepared by dispersing at least one clay material in a water dissipatible polymer to form a platelet particle dispersion; introducing said platelet particle dispersion to a polyester and extrusion mixing said dispersion and polyester.
