Method for producing foamed-in-mold product of aromatic polyester based resin |
摘要 |
The present invention provides a process for producing a molded foam article of a crystalline aromatic polyester resin. The process is characterized by heating the surface temperature of a mold for cavity-molding to the temperature within a range of from (td+35) to (Tg+57)°C. (Tg is a glass transition temperature of the crystalline aromatic polyester resin prepuffs), thereby to mold prepuffs, and cooling the surface of the mold to a temperature not lowered than Tg for at least 20 seconds.
