Provided is a polyolefin-based resin composition having sufficient stabilizing effect and excellent cost performance. The polyolefin-based resin composition according to the present invention comprises a polyolefin-based resin obtained by polymerization of an olefin-based monomer with an addition of a phenolic antioxidant represented by the following Formula (I):
(wherein, R represents a C 1 -C 30 alkyl group or C 2 -C 30 alkylene group which is optionally branched and/or optionally has a cycloalkyl group, a C 3 -C 12 cycloalkyl group which is optionally substituted or a C 6 -C 18 aryl group which is optionally substituted),
which phenolic antioxidant is masked with an organic aluminum compound, and a phosphorus-based antioxidant to a catalyst system or polymerization system before or during the polymerization of the olefin-based monomer, in which polyolefin-based resin composition, the phenolic antioxidant represented by the Formula (I) and the phosphorus-based antioxidant are added in an amount of 0.001 to 0.5 parts by mass and 0.001 to 3 parts by mass, respectively, with respect to 100 parts by mass of the olefin-based monomer. |
