摘要

PROBLEM TO BE SOLVED: To provide reclaimed foamable styrenic resin particles giving molded articles having excellent appearances and strengths, to provide a method for producing the same, to provide reclaimed styrenic foamed beads, and to provide reclaimed foamed styrenic resin molded articles.;SOLUTION: This reclaimed foamable styrenic resin particles which each comprise a nucleus comprising a recycled styrenic resin, and a virgin styrenic resin encapsulating the nucleus is characterized in that the central portion for forming up to 1/5 from the center has a weight-average mol.wt. of 150,000 to 250,000, when the particle is divided into five divisions from the surface to the center, and a ratio [(B)/(A)]×100 (%) is 110, wherein (A) is the weight-average mol.wt. of the resin particles; (B) is the weight-average mol.wt. of surface portions for forming up to 1/5 from the surface of each resin particle to the center; and further a ratio [(b)/(A)]×100 (%) is 130, wherein (A) is the weight-average mol.wt. of the resin particles; (b) is the weight-average mol.wt. of the most surface portions for forming up to 1/6 from the surface of each resin particle to the center.;COPYRIGHT: (C)2006,JPO&NCIPI
