  The present invention provides a modifier for aromatic polyesters which enhances the melt fluidity of aromatic polyesters without a significant decrease in the heat resistance of the aromatic polyesters, and an aromatic polyester resin composition including the modifier for aromatic polyesters. The present invention relates to a modifier for aromatic polyesters comprising polyhydric phenol residues and residues of aromatic polycarboxylic acid, acid halide or acid anhydride thereof, and the modifier comprises a material having a structure composed of a first residue selected from the group consisting of divalent residues represented by Formula (I): —Ar—W 1 x —Ar— and by Formula (II): —Ar—, the first residues being bonded to two identical or different second residues selected from the group consisting of monovalent residues represented by Formula (III): and monovalent residues represented by Formula (IV): —O—C(O)—R 7 —.

  本发明提供了一种用于芳香族聚酯的改性剂，可以增强芳香族聚酯的熔融流动性，而不明显降低芳香族聚酯的耐热性，以及包括该改性剂的芳香族聚酯树脂组合物。本发明涉及一种用于芳香族聚酯的改性剂，包括多羟基酚残基和芳香族多羧酸、酸卤或其酸酐残基，该改性剂包括具有以下结构的材料：第一残基，选择自由式(I)所代表的二价残基：—Ar—W1x—Ar—和自由式(II)所代表的：—Ar—，第一残基与选择自由式(III)所代表的单价残基：和自由式(IV)所代表的单价残基：—O—C(O)—R7—的两个相同或不同的第二残基结合。

  The present invention provides an aromatic polyester which is substantially free from the occurrence of coloration and retains significantly high transparency even after being thermally processed at high temperature and which has high flowability. The aromatic polyester contains a polyhydric phenol residue and a residue of any one of aromatic polycarboxylic acid, halide thereof, and anhydride thereof, and terminals of the aromatic polyester have a structure represented by the formula -C(O)-R. The aromatic polyester has an end-capping rate of 90% or higher and a weight average molecular weight (Mw) ranging from 3,000 to 1,000,000.

  本发明提供了一种芳香族聚酯，该聚酯基本上不会发生着色，即使在高温热加工后仍能保持明显的高透明度，并且具有高流动性。芳香族聚酯含有多羟基苯酚残留物和芳香族多羧酸、其卤化物和其酸酐中任意一种的残留物，芳香族聚酯的端基具有式 -C(O)-R 所代表的结构。芳香族聚酯的端盖率为 90% 或更高，重量平均分子量（Mw）为 3,000 至 1,000,000 之间。
