PURPOSE:To obtain the subject mixture, capable of sufficiently providing characteristics of respective resins and further improved in improved strength of brittleness by adding a diglycidyl ester-based compound and a specific metallic compound to specified two kinds of the resins, melt mixing the mixture in an extruder and extruding the resultant molten mixture. CONSTITUTION:The objective mixture is obtained by adding 0.1-2 pts.wt. diglycidyl ester-based compound (e.g. diglycidyl terephthalate), 0.02-0.5 pt.wt. compound of a group I to II metal of the periodic table (e.g. sodium carbonate) and a foaming agent such as gaseous carbon dioxide to a thermoplastic polyester-based resin and a thermoplastic polyamide-based resin, melt mixing the mixture in an extruder and then extruding the resultant molten mixture at >=200 deg.C extrusion temperature. |
