Abstract

PURPOSE:To obtain the polyester foaming which is easily drawn and processed thermally by extruding aromatic polyester, which contains a substance, the boiling point thereof at normal pressure is 90 deg.C or lower, and has specified melting viscosity, from a die under a specified condition and foaming it. CONSTITUTION:The aromatic polyester, which contains the 1-50wt% substance, the boiling point thereof at normal pressure is 90 deg.C or lower, and melting viscosity thereof at a temperature higher than the melting point by 15 deg.C is 8,000 poise or higher, is prepared. Preferably, a diepoxy compound and metal in the Ia or IIa group of the Periodic Table and the like are jointly used and added to the aromatic polyester at that time. The melted substance is extruded from the die under the condition that satisfies a formula I [t1/2 shows semicrystallization time (sec) at a temperature indicating the maximum crystallization speed of polyester and D an effective diameter (cm) of the foaming body] and foamed and the stringy foaming body with a 1-200mm.<2> sectional area is manufactured.
