    • The present invention relates to a process for producing an aramid silicone polymer. The present invention is characterized by reacting (A) a both-terminal amino-modified diorganopolysiloxane having a group represented by the following formula: —B—NH2 wherein B represents a divalent hydrocarbon group, at both terminals of a molecular chain, (B) an aromatic diamine, and (C) an aromatic dicarboxylic acid dihalide, in the presence of (D) an inorganic base, in (S1) water and (S2) an aprotic organic solvent, at a temperature of 10° C. or more. The present invention does not have to be carried out at a low temperature, and by-products can be easily treated. Furthermore, the present invention does not require a large amount of a reprecipitation solvent, and therefore it can be suitably used in mass production of an aramid silicone polymer.
    • 本发明涉及芳族聚酰胺硅氧烷聚合物的制备方法。 本发明的特征在于:(A)具有由下式表示的基团的双末端氨基改性二有机聚硅氧烷:B-NH 2,其中B表示二价烃基,在分子链的两个末端,(B) 芳族二胺和(C)芳族二羧酸二卤化物,在(D)无机碱存在下,在(S1)水中和(S2)非质子性有机溶剂中,在10℃以上的温度下进行。 本发明不必在低温下进行,副产物可以容易地处理。 此外,本发明不需要大量的再沉淀溶剂,因此可以适当地用于大量生产芳族聚酰胺硅氧烷聚合物。
