Disclosed is a resin composition provided with excellent mold releasability and anti-blocking properties. Specifically disclosed is a 4-methyl-1-pentene polymer-containing resin composition which contains 0.01-10 parts by mass of a 4-methyl-1-pentene polymer (B) per 100 parts by mass of at least one resin (A) selected from the group consisting of thermoplastic resins and thermosetting resins.  The 4-methyl-1-pentene polymer-containing resin composition is characterized in that (B1) the 4-methyl-1-pentene polymer (B) has a limiting viscosity [?] as measured in a decalin solvent at 135°C within the range of not less than 0.01 dl/g but less than 0.50 dl/g. La présente invention concerne une composition de résine dotée d'excellentes propriétés de démoulage et d'anti-adhésion. L'invention concerne spécifiquement une composition de résine contenant un polymère du 4-méthyl-1-pentène qui contient 0,01-10 parties en masse d'un polymère du 4-méthyl-1-pentène (B) pour 100 parties en masse d'au moins une résine (A) choisie dans le groupe constitué par des résines thermoplastiques et des résines thermodurcissables. La composition de résine contenant un polymère du 4-méthyl-1-pentène est caractérisée en ce que (B1) le polymère du 4-méthyl-1-pentène (B) a une viscosité intrinsèque [?] mesurée dans un solvant décaline à 135 °C dans la plage non inférieure à 0.01 dl/g mais non inférieure à 0,50 dl/g.
