POLYARYLATE

PROBLEM TO BE SOLVED: To provide a polyarylate especially preferably used for a multi-layered film, a multi-layered sheet or a multi-layered blow moldings or the like, because of a small coefficient of volume expansion, outstanding high dimensional stability and superior heat-resistance. SOLUTION: T...

Summary:PROBLEM TO BE SOLVED: To provide a polyarylate especially preferably used for a multi-layered film, a multi-layered sheet or a multi-layered blow moldings or the like, because of a small coefficient of volume expansion, outstanding high dimensional stability and superior heat-resistance. SOLUTION: The polyarylate comprises a structural unit introduced from 4-hydroxy-benzoic acid, 2,6-naphthalene dicarboxylic acid or hydroquinone in a specific ratio, and shows an optical anisotropy when melted.
