    摘要: A polymer is swollen in a first tank. The swelling temperature is in the range of −10 to 50° C. The mixture is cooled in a first cooling vessel to the range of −100 to −10° C., and thereafter heated in a heating device to the range of 0 to 57° C. The polymer is cellulose acylate in which a degree of substitution of the acyl group for hydroxyl group is at least 2.87. A film obtained from the cellulose acylate has a negative value of ΔRe and a positive value of ΔRth, and |ΔRth| is at least 10 nm. ΔRe and ΔRth are respective difference of Re and Rth at the measurement thereof with use of wavelengths between 700 nm and 400 nm. The film is used adequately as a birefringence film, a protective film for a polarizing filter in a liquid crystal display.
