| titleOfInvention | Liquid-crystalline polyester and process for preparing same |
| abstract | The present invention relates to a kind of liquid crystalline polyester, it is characterized in that, by following structural unit (I), (II), (III), (IV) and (V) form, structural unit (I) is relative to structural unit (I), (II) and (III) add up to 68 ~ 80 % by mole, structural unit (II) adds up to 55 ~ 75 % by mole relative to structural unit (II) and (III's), structural unit (IV) adds up to 60 ~ 85 % by mole relative to structural unit (IV) and (V's), the total of structural unit (II) and (III) and the total of (IV) and (V) to be essentially etc. mole, the Δ S (entropy of melting) defined by following formula ［ 1 ］ is 1.0 ~ 3.0 × 10n -3 j/gK.(Tm refers to: in the differential calorimetry of liquid crystalline polyester in Δ S (J/gK)=Δ Hm (J/g)/Tm (K) ［ 1 ］, the endotherm peak temperature (Tm1) that observation observes when measuring under the Elevated Temperature Conditions of 20 DEG C/min from room temperature, then after the temperature of Tm1+20 DEG C keeps 5 minutes, temporarily room temperature is cooled under the cooling conditions of 20 DEG C/min, the endotherm peak temperature (Tm2) that observation observes when again measuring under the Elevated Temperature Conditions of 20 DEG C/min, then after the temperature of Tm1+20 DEG C keeps 5 minutes, temporarily room temperature is cooled under the cooling conditions of 20 DEG C/min, the endotherm peak temperature (Tm3) observed when again measuring under the Elevated Temperature Conditions of 20 DEG C/min, Δ Hm is the endotherm(ic)peak area (Δ Hm3) of this Tm3.)。 |
