    • The present invention is concerned with thermoplastic terephthalic acid copolyesters which crystallize more rapidly than homopolyethylene terephthalate and are based on a diol component which is about 98 to 99.9 mol % of ethylene glycol and the balance 2-ethylhexane-1,3-diol. The acid component may be up to about 10.0 mol % of other than terephthalic acid or its dimethyl ester.This invention is also concerned with a process of synthesizing such copolyesters by esterifying or transesterifying the acid and diol components between about 150.degree. and 250.degree. C. in the presence of appropriate catalysts. The condensation product may be subject to polycondensation at about 200.degree. to 300.degree. C. under reduced pressure in the presence of esterification catalysts. In a preferred embodiment the 2-ethylhexane-1,3-diol is added after the initial reaction between the acid component and the ethylene glycol and preferably after the degree of polycondensation is greater than 4.
    • 本发明涉及热塑性对苯二甲酸共聚酯,其比对苯二甲酸聚对苯二甲酸丙二醇酯更快地结晶,并且基于约98-99.9摩尔%的乙二醇和余量的2-乙基己烷-1,3-二醇的二醇组分。 除了对苯二甲酸或其二甲酯之外,酸组分可以高达约10.0mol%。 本发明还涉及通过在合适的催化剂存在下在约150℃和250℃之间酯化酯化或酯交换合成这种共聚酯的方法。 在酯化催化剂存在下,缩合产物可在减压下在约200℃至300℃下进行缩聚反应。 在优选的实施方案中,在酸组分和乙二醇的最初反应之后,优选在缩聚度大于4之后加入2-乙基己烷-1,3-二醇。

    • A composite plastic structure is described. The composite structure includes: (a) a shaped polycarbonate article having an edge region, the edge region having an adhesion-promoting geometric feature therein; (b) a coating applied to the surface of the shaped polycarbonate article; and (c) a polymer that is injection-molded or cast over the edge region of the shaped polycarbonate article. The polymer (c) envelopes the adhesion-promoting geometric feature of the shaped polycarbonate article (a). The envelopment of the adhesion-promoting geometric feature by the polymer (c) provides a structurally firm connection between the shaped polycarbonate article (a) and the polymer (c). Also described is a method of preparing the composite structure, and composite structures according to the present invention, such as picture frames, slide frames, windows having a seal or frame, and a glazing for a motor vehicle.
