Title: LIQUID-CRYSTAL POLYESTER COMPOSITION
Abstract:
A liquid-crystal polyester composition including a liquid-crystal polyester and glass fibers, the liquid-crystal polyester composition satisfying conditions (i) and (ii). (i) The flow initiation temperature of the liquid-crystal polyester composition is 330°C or higher. (ii) The value of 100 × b/a is 50-200, where a is the area ratio of the peak area at a retention time of 21.90 minutes to the peak area at a retention time of 2.50 minutes in a chromatogram of degradation products obtained by degrading the liquid-crystal polyester composition by n-butylamine, and b is the area ratio of the peak area at a retention time of 21.90 minutes to the peak area at a retention time of 2.50 minutes in a chromatogram of degradation products obtained by degrading a liquid-crystal composition obtained by holding the liquid-crystal polyester composition for one hour at a temperature 30°C higher than the flow initiation temperature by n-butylamine.
