    • The present invention provides a method capable of producing an olefin resin composition for a home electric appliance materials and automotive interior materials that has good color tone and shows excellent fogging resistance, in which method the total amount of stabilizer(s) to be added is reduced and cost reduction can thus be attained. The method of producing an olefin resin composition for an automotive interior material by polymerization of an olefin monomer according to the present invention is characterized by comprising the step of adding, before or during the polymerization of an olefin monomer, 0.001 to 0.5 parts by mass of a phenolic antioxidant, which is represented by the following Formula (1) and masked with an organoaluminum compound, with respect to 100 parts by mass of an olefin resin obtained by the polymerization: (wherein, R represents an alkyl group having 1 to 30 carbon atoms which is optionally branched, a cycloalkyl group having 3 to 12 carbon atoms which is optionally substituted or an aryl group having 6 to 18 carbon atoms which is optionally substituted).
    • 本发明提供一种能够制造家用电器材料的烯烃树脂组合物和具有良好的色调并且具有优异的抗雾性的汽车内部材料的方法,其中加入的稳定剂的总量降低 从而可以实现成本降低。 通过本发明的烯烃单体的聚合制造汽车内部材料的烯烃树脂组合物的方法的特征在于包括在烯烃单体的聚合之前或期间加入0.001至0.5质量份的 相对于100质量份通过聚合得到的烯烃树脂,其由下式(1)表示并被有机铝化合物掩蔽的酚类抗氧化剂(其中,R表示具有1〜30个碳原子的烷基 任选支化的原子,任选取代的具有3至12个碳原子的环烷基或任选被取代的具有6至18个碳原子的芳基)。
