titleOfInvention |
Crystalline wholly aromatic polyester and polyester resin composition |
abstract |
The invention provides a crystalline wholly aromatic polyester that is capable of improving slidability and thermal stability at the time of molding, while having heat resistance. The crystalline wholly aromatic polyester is a polycondensate of an aromatic dicarboxylic acid and an aromatic diol, wherein a structural unit derived from the aromatic dicarboxylic acid comprises structural unit (I) of formula (1): n n n n n n n n n n structural unit (II) of formula (2): n n n n n n n n n n and structural unit (III) of formula (3): n n n n n n n n n n and a structural unit derived from the aromatic diol comprises structural unit (IV) of formula (4): n n n n n n n n n n wherein 30 mol %≤structural unit (I)≤40 mol %; 5 mol %≤structural unit (II)≤10 mol %; 5 mol %≤structural unit (III)≤10 mol %; and 45 mol %≤structural unit (I)+structural unit (II)+structural unit (III)≤50 mol %. |
