<p><P>PROBLEM TO BE SOLVED: To provide a new polymer stabilizer for imparting excellent working stability to a polymer composition when a polymer is molded at high temperature. <P>SOLUTION: The polymer stabilizer contains a 13-20C condensed polycyclic hydrocarbon having a structure represented by formula (1) (X denotes an oxygen atom or a sulfur atom), wherein, the condensed polycyclic hydrocarbon has aromatic properties, an oxygen atom, a nitrogen atom and a sulfur atom may be substituted for each of carbon atoms which constitute the condensed polycyclic hydrocarbon, and a halogen atom, a cyano group, a 1-4C alkyl group, a 1-4C alkoxy group, a 1-4C alkylthio group or a 6-12C aryl group may be substituted for each of hydrogen atoms contained in the condensed polycyclic hydrocarbon. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
