    • A diallyl terephthalate prepolymer is here disclosed which essentially has the following structureCH.sub.2 .dbd.CHCH.sub.2 O(COArCOOBO).sub.n COArCOOCH.sub.2 CH.dbd.CH.sub.2wherein B is a divalent organic residue derived from a diol having 2 to 20 carbon atoms, Ar is a 1,4-phenylene group, and n is a value of 1 to 100, and having an unsaturation in a range of 20 to 100, as represented by an iodine value determine by the Wijs method, and there is also disclosed a method for preparing the diallyl terephthalate prepolymer.The method of the present invention permits obtaining the allyl prepolymer having excellent physical properties from inexpensive raw materials with less labor.Since this prepolymer has a double bond suitably, it can be mixed with unsaturated polyester resin or diallyl phthalate resin, when used. Moreover, the prepolymer can be also used as a crosslinking agent for EPR, elaslene, synthetic rubber and the like.
    • 此处公开了二烯丙基对苯二酸酯预聚物,其基本上具有以下结构CH 2 = CHCH 2 O(COArCOOBO)n COArCOOCH 2 CH = CH 2其中B是衍生自具有2至20个碳原子的二醇的二价有机残基,Ar是1,4-亚苯基, n为1〜100,不饱和度为20〜100,以由Wijs法测定的碘值表示,并且还公开了对苯二甲酸二烯丙酯预聚物的制备方法。 本发明的方法可以从较便宜的原料获得具有优异物理性能的烯丙基预聚物,而且劳动力少。 由于该预聚物适当地具有双键,因此可以在使用时与不饱和聚酯树脂或邻苯二甲酸二烯丙酯树脂混合。 此外,预聚物也可以用作EPR,金刚石,合成橡胶等的交联剂。
