A polarizing film comprising
- a hydrophobic polymer and a dichroic dye,
- wherein the hydrophobic polymer comprises a polypropylene polymer comprising about 0.5 mol % or less of an ethylene content (mol %), and has a distribution of a molecular weight of about 1 to about 5.
A method of manufacturing a polarizing film, comprising
- polymerizing a propylene monomer using a zirconocene catalyst or a hafnocene catalyst to prepare a polypropylene polymer comprising about 0.5 mol % or less of an ethylene content (mol %), and having a distribution of a molecular weight of about 1 to about 5,
- melt-blending a hydrophobic polymer comprising the polypropylene polymer and a dichroic dye at a temperature of greater than or equal to a melting point of the hydrophobic polymer,
- molding the melt-blend, and
- elongating a molded body.
