Abstract: front page image
(EN)A wholly aromatic liquid crystal polyester containing 2.0-15.0 mol% of hydroquinone-derived structural units relative to the total amount of structural units, the wholly aromatic liquid crystal polyester being characterized in that the amount of hydroxyl terminal groups (a) and the amount of acetyl terminal groups (b) constitutes a total of 50-350 eq/(g∙10-6), and the total of the amount of hydroxyl terminal groups (a) and the amount of acetyl terminal groups (b), and the amount of carboxyl terminal groups (c) are in a ratio [(a) + (b)]/(c) of 1.05-2.00.
(FR)L'invention concerne un polyester à cristaux liquides, totalement aromatique, contenant 2,0-15,0 % en moles d'unités structurales issues de l'hydroquinone par rapport à la quantité totale d'unités structurales, le polyester à cristaux liquides, totalement aromatique, étant caractérisé en ce que la quantité de groupes terminaux hydroxyle (a) et la quantité de groupes terminaux acétyle (b) représente un total de 50-350 éq/(g•10-6), et le total de la quantité de groupes terminaux hydroxyle (a) et de la quantité de groupes terminaux acétyle (b) et la quantité de groupes terminaux carboxyle (c) sont dans un rapport [(a) + (b)]/(c) de 1,05-2,00.
(JA)構造単位全量に対してハイドロキノン由来の構造単位を2.0~15.0モル%含有する全芳香族液晶ポリエステルであり、ヒドロキシ末端基量(a)とアセチル末端基量(b)の合計が50~350当量/(g・10-6)であり、ヒドロキシ末端基量(a)とアセチル末端基量(b)の合計と、カルボキシ末端基量(c)との比[(a)+(b)]/(c)が1.05~2.00であることを特徴とする全芳香族液晶ポリエステル。
