Method for producing transparent polymer film, transparent polymer film produced by the method, retardation film, polarizer, and liquid-crystal display device
摘要:
A method for producing a transparent polymer film, comprising heat-treating a polymer film containing a polymer and a plasticizer having a number-average molecular weight of from 500 to 10000 and having a repetitive unit, at a temperature T (unit, ° C.) satisfying the following formula (1): Tc≦T
