摘要： An object of the present invention is to provide an aromatic polyester-based resin foam molded product having excellent mechanical properties, foamed aromatic polyester-based resin particles for producing the foam molded product, or a method for producing the foamed particles. The present invention relates to foamed aromatic polyester-based resin particles, wherein crystallinity (A) in a particle central portion and crystallinity (B) in a particle surface layer are both 10% or less, and a ratio of the crystallinity in the surface layer to the crystallinity in the central portion (B/A) is 0.3 to 1.4.

摘要： A thermoplastic resin foam including a thermoplastic resin, wherein: the thermoplastic resin includes a polyester resin and a polyimide resin, and the thermoplastic resin foam shows a single glass transition temperature Tg. The glass transition temperature of the thermoplastic resin is preferably 80 to 130° C. An absolute value of difference between heat absorption and heat generation, each determined by heat flux differential scanning calorimetry at a heating rate of 10° C./min, is preferably 3 to 35 J/g.
