Estimating the term…
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.
A process comprising the steps of dispersing a chalcogen or at least one clay material in a water dissipatible polymer to form a platelet particle dispersion;
A process for preparing a polyester composite material comprising the steps of:
The process of claim 29 wherein the polyesters and polyesteramides are derived from monomer components selected from the group consisting of dicarboxylic acid, hydroxycarboxylic acid, aminocarboxylic acid, aminoalcohol, glycol, diamine or combinations thereof wherein at least a part of the total of all such monomer components is poly(ethylene glycol), and at least a part of the total is one or more of the monomer components substituted with one or more sulfonate metal salt groups.
