POLYARYLATE AND MOLDED ARTICLE USING SAME

摘要

The present invention can provide a polyarylate obtained from a dihydric phenol component and an aromatic dicarboxylic acid component. The polyarylate is characterized in that the dihydric phenol component contains a compound represented by general formula (A) or (B) as a primary raw material, and the pencil hardness of the polyarylate is H or higher.;;(In the formula, R1 and R2 each independently denote a hydrogen atom, an alkyl group having 1-6 carbon atoms or a phenyl group. However, neither R1 nor R2 represents a methyl group.);;(In the formula, R3 and R4 each independently denote a hydrogen atom or a methyl group. In addition, a is an integer between 4 and 11. However, a is not 5 if R3 and R4 are both hydrogen atoms.)

1. A polyarylate obtained from a dihydric phenol component and an aromatic dicarboxylic acid component, wherein the dihydric phenol component contains a compound represented by general formula (A) or (B) as a primary raw material, and wherein the pencil hardness of the polyarylate is a or higher:wherein in the formula, R1 and R2 each independently represent a hydrogen atom, an alkyl group having 1 to 6 carbon atoms or a phenyl group, but neither R1 nor R2 represents a methyl group;wherein in the formula, R3 and R4 each independently represent a hydrogen atom or a methyl group, and a is an integer of 4 to 11, but a is not 5 if R3 and R4 are both hydrogen atoms.
