PROCESS FOR PRODUCING A CRYSTALLINE AROMATIC POLYESTER RESINMOLDED FOAM ARTICLE

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 (Tg + 35) to (Tg + 57).degree. C (Tg is a glass transition temperatu re 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.
