摘要:
Disclosed is a negative C-type retardation compensator for a liquid crystal display. The negative C-type retardation compensator for the liquid crystal display includes polyarylate having a thio group or a sulfur oxide group in a polymer main chain thereof. Accordingly, the retardation compensator has an absolute value of negative retardation that is larger in a thickness direction than a retardation compensator which includes polyarylate having no thio group or sulfur oxide group in a polymer main chain thereof even though the retardation compensator having the thio group or sulfur oxide group and the retardation compensator having no thio group or sulfur oxide group are the same as each other in thickness. Thereby, the negative C-type retardation compensator for liquid crystal displays is capable of being desirably applied to the liquid crystal displays.

摘要:
The present invention relates to a process for preparing polyarylate, and more specifically, to a process for preparing polyarylate by interfacial polymerization of a bivalent phenol compound and an aromatic dicarboxylic acid or a halide thereof, which comprises mixing a cationic catalyst for the phase transition and a nonionic surfactant in a predetermined ratio, to further increase the yield of polyarylate, as compared with the case of using each of the nonionic surfactant and the cationic catalyst for the phase transition alone.
