    • A process for producing a film-like or fibrous structure of an aromatic polyester, which comprises(1) forming an unstretched film-like or fibrous structure by melt-shaping a blend comprising 100 parts by weight of (A) an aromatic polyester having a high degree of polymerization derived from an aromatic dicarboxylic acid as a main acid component and an aliphatic diol and/or an alicyclic diol as a main glycol component and (B) 3 to 300 parts by weight of a low-molecular-weight compound being substantially non-reactive with the aromatic polyester (A) and having a boiling point of at least about 200.degree. C. under atmospheric pressure and a molecular weight of not more than 1,000,(2) stretching the resulting film-like or fibrous structure,(3) extracting at least a major portion of the low-molecular-weight compound from the stretched film-like or fibrous structure by using an organic solvent which does not substantially dissolve the aromatic polyester under the extracting conditions, and(4) if desired, heat-setting the film-like or fibrous structure after the stretching step (2) and/or the extracting step (3).The film-like or fibrous structure of an aromatic polyester prepared by the process substantially contains no low-molecular-weight compound or contains the low-molecular-weight compound in an amount of up to about 1 part by weight at most per 100 parts by weight of the aromatic polyester.
    • 一种制备芳族聚酯的薄膜状或纤维结构体的方法,其包括:(1)通过熔融成型共混物形成未拉伸的薄膜状或纤维结构体,所述共混物包含100重量份的(A)具有 衍生自作为主要酸成分的芳族二羧酸和作为主要二醇成分的脂族二醇和/或脂环族二醇的高聚合度和(B)基于3〜300重量份的低分子量化合物 与芳族聚酯(A)不反应,并且在大气压下沸点至少为约200℃,分子量不大于1000,(2)拉伸所得膜状或纤维结构物( 3)通过使用在萃取条件下基本上不溶解芳香族聚酯的有机溶剂,从拉伸膜状或纤维结构体中提取至少一部分低分子量化合物,和( 4)如果需要,在拉伸步骤(2)和/或提取步骤(3)之后对膜状或纤维结构进行热定型。 通过该方法制备的芳族聚酯的薄膜状或纤维结构基本上不含低分子量化合物,或者含有最多约1重量份至100重量份的低分子量化合物 芳香族聚酯的重量。

    • A process for producing a thermoset resin, which comprises reacting (A) a poly(cyclic iminoether), (B) an ethylenically unsaturated compound having a functional group reactive with the poly(cyclic iminoether), and (C) an ethylenically unsaturated monomer having no functional group reactive with the poly(cyclic iminoether), in the presence of an acid catalyst and a radical catalyst. Instead of the compound (B), there may be used the compound (D), i.e. a compound having at least two equivalents of at least one group selected from the class consisting of carboxyl, hydroxyl, amino, epoxy and carboxylic anhydride groups in the molecule and being free from an ethylenically unsaturated bond. The present application provides also a thermosetting composition and a thermoset resin.
