<p>Provided is a method of producing a laminate film by which a laminate film having excellent adhesion with a laminate base material, in which laminate film the amount of elution of an additive into a solvent is small, can be produced. The method of producing a laminate film is characterized by comprising the step of adding, before or during polymerization of a monomer having an ethylenically unsaturated bond, a phenolic antioxidant represented by the following Formula (1), which is masked with an organoaluminum compound, to at least one of a catalyst system, a polymerization system and a piping, such that the phenolic antioxidant is incorporated in an amount of 0.001 to 0.5 parts by mass with respect to 100 parts by mass of a polymer obtained by the polymerization:
(wherein, R 1 and R 2 each independently represent a hydrogen atom, an alkyl group having 1 to 5 carbon atoms which is optionally branched, or the like; and R represents an alkyl group having 1 to 30 carbon atoms which is optionally branched, an alkenyl group having 2 to 30 carbon atoms which is optionally branched, or the like).</p> |
