    • A process for producing a highly reactive modified phenolic resin, comprising the steps of polycondensing a petroleum heavy oil or pitch, a formaldehyde polymer and a phenol in the presence of an acid catalyst to thereby prepare a modified phenolic resin; and reacting the resultant modified phenolic resin with a phenol in the presence of an acid catalyst but in the absence of a crosslinking agent such as a formaldehyde polymer to thereby lower the molecular weight of the modified phenolic resin. This highly reactive modified phenolic resin has a low number average molecular weight and a high phenol content, so that its resin melt viscosity is low and that it exhibits a markedly improved reactivity with an epoxy resin. Accordingly, the combination thereof with an epoxy resin provides a molding material suitable for producing a molding which is excellent in not only thermal resistance and moldability but also dimensional stability and other mechanical properties, especially a material for electrical or electronic part and a semiconductor sealer.
    • 一种生产高反应性改性酚醛树脂的方法,包括在酸催化剂存在下使石油重油或沥青,甲醛聚合物和苯酚缩聚的步骤,从而制备改性酚醛树脂; 在酸催化剂的存在下,使所得改性酚醛树脂与苯酚反应,但不存在交联剂如甲醛聚合物,从而降低改性酚醛树脂的分子量。 该高反应性改性酚醛树脂具有低的数均分子量和高的苯酚含量,使得其树脂熔体粘度低,并且显示出与环氧树脂显着改善的反应性。 因此,与环氧树脂的组合提供了适合于制造不仅具有优异的耐热性和成型性,而且尺寸稳定性和其它机械性能优异的成型体的成型材料,特别是电气或电子部件的材料以及半导体密封剂。

    • A process for producing a mesophase pitch based active carbon fiber, comprising the steps of carbonizing a mesophase pitch based infusibilized fiber at 600 to 900null C., activating the thus obtained carbon fiber with alkali, and immersing the thus obtained mesophase pitch based active carbon fiber in an electrolyte and subjecting the immersed mesophase pitch based active carbon fiber to such a charge and discharge treatment that a voltage gradually increased until exceeding 2.5 V is applied at a constant current density to the mesophase pitch based active carbon fiber so that an electric double layer is formed at an interface of the mesophase pitch based active carbon fiber and the electrolyte to thereby effect a charging and thereafter a discharging is effected at a constant current density. There are further provided an active carbon fiber produced by the above process and an electric double layer capacitor including an electrode comprising this active carbon fiber.
    • 一种制备中间相沥青基活性炭纤维的方法,包括以下步骤:在600-900℃下对中间相沥青基不熔化纤维进行碳化,用碱活化所得到的碳纤维,并将由此获得的中间相沥青基活性炭 纤维在电解质中并使浸入的中间相沥青基活性炭纤维进行这样的充放电处理,使得电压逐渐增加直到超过2.5V以恒定电流密度施加到中间相沥青基活性炭纤维上,使得电双 在中间相沥青基活性炭纤维和电解质的界面处形成层,从而进行充电,然后以恒定电流密度进行放电。 还提供了通过上述方法制造的活性炭纤维和包括这种活性碳纤维的电极的双电层电容器。
