AROMATIC POLYESTER-BASED RESIN FOAM PARTICLES FOR IN-MOLD FOAM MOLDING, METHOD FOR PRODUCING SAME, IN-MOLD FOAM MOLDED BODY, COMPOSITE STRUCTURAL MEMBER, AND MEMBER FOR AUTOMOBILE

摘要

The present invention provides aromatic polyester-based resin foam particles for in-mold foam molding, whereby it is possible to produce an in-mold foam molded body having a long post-production storage life and also offering excellent mechanical strength and outer appearance. These aromatic polyester-based resin foam particles for in-mold foam molding are characterized in comprising an aromatic polyester-based resin and in that the residual ratio of carbon dioxide when 7 hours have elapsed since 24 hours of impregnation with the carbon dioxide under conditions of 25°C and 1 MPa is 5 wt% or more.
