POROUS MOLDED OBJECT AND PROCESS FOR PRODUCING SAME

摘要

A porous molded object having excellent heat-insulating properties and high brightness, and a process for producing the molded object. The process for producing the porous molded object is characterized by cooling a parison comprising a crystalline polymer and/or a polymer containing fine particles, thereby forming particles serving as seed particles for void formation, and blow-molding the parison to produce a molded object having voids therein.
