<P>PROBLEM TO BE SOLVED: To reduce the use amount of an antistatic and prevent the electrostatic charge in a foam molded article composed of a resin composition containing a polylactic acid-based resin and the polymer-type antistatic. <P>SOLUTION: There is provided the polylactic acid-based resin foam molded article formed of the resin composition comprising the polylactic acid-based resin and the polymer-type antistatic, wherein the polylactic acid-based resin composition further comprises at least one of a polyolefinic resin and a polystyrenic resin, and thereby, a dispersion phase containing at least one of the polyolefinic resin and the polystyrenic resin and a matrix phase containing the polylactic acid-based resin are formed at least on the molded article surface; and as the antistatic, a polymer-type antistatic is used which has a lower solubility parameter than that of the polylactic acid-based resin, and thereby, the dispersion phase forming a core-shell particle having the polymer-type antistatic as an outer shell is formed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
