The present application relates to a polymer film and a method for producing a polarizing plate. The present application can provide a polymer film satisfying optical and mechanical durability required in a polarizing plate effectively and capable of forming a polarizing plate without causing bending when applied to a display device, and a method for producing a polarizing plate to which the polymer film is applied. The present application can provide a polymer film capable of realizing the required optical and mechanical durability without causing bending even in a polarizing plate applied to a thin display device and/or a thin polarizing plate, and a method for producing a polarizing plate to which the polymer film is applied.

Damage of the outer surface of a rubber hose due to friction can be prevented while the sealing performance and the productivity are ensured. The following components are provided: a pipe 11 whose one end is connected to a vulcanization pipe and in which pressed liquid is pumped from an inlet 11a disposed at the side face of the other end side; an annular member 12 which is attached to the pipe 11 so as to close an opening of the other end side of the pipe 11, and includes a hole 12a whose diameter is larger than the outer diameter of a rubber hose and in which the rubber hose passes through; and a pump which pumps more liquid than the liquid discharged outside the pipe 11 through the gap between the hole 12a and the rubber hose into an inlet 11a.

A hollow-cylindrical device (1) having first and second openings (2, 3) for continuous production of a dental composite block. A curable composite material (4) and a temperature control unit (5) are provided. The composite material (4) is introduced into the device (1) through the first opening. The composite material (4) is cured by energy from the temperature control unit (5). An energy input occurs across a defined length of the substantially hollow-cylindrical device (1) and/or for a defined period of time. The composite material (4) is subsequently guided through the first opening (2) of the device (1). The composite material (4) is discharged from the second opening (3). In a first region along a portion of the length of the device, the device is either provided with an insulation or the flow-through device has a heat conductivity of 0.05 to 12 W/(m×K).
