Abstract
PURPOSE: To manufacture a foamed article having excellent appearance and uniformly dispersed fine bubbles, stably, by adding a diepoxide compound and montan wax to a polyester during melt-molding process.
CONSTITUTION: A polyester composition composed of (A) an aromatic polyester (e.g. polyethylene terephthalate), (B) 0.05W5wt% of a diepoxide compound, (C) 0.05W3wt% of a montan wax salt and/or montan wax ester salt, is incorporated with (D) 0.05W50wt%, based on the above composition, of a substance having a boiling point of ≤200°C (pref. ≤ 150°C) at atmospheric pressure (e.g. inert gas such as CO2, organic compound, etc.) dissolved into said composition under pressure. The whole composition is foamed by melt-extrusion
