Compositions containing polyorganosiloxanes having polyphenylene ether groups

The invention relates to a method for producing a composition in which a) a compound selected from the group consisting of hydroxyl-terminated homo-or copolymerized polyphenylene ether and phenols is reacted with b) a chlorosilane of formula (I), alone or mixed with a disiloxane of formula (IV), in the presence of water and a solvent, R1 aR2bSiCl4-a-b (I) [R1 (3-b) R2bSi] 2O (IV) wherein R1, R2, a and b are as defined in claim 1; to a composition obtainable by this process; and to the use of said composition as a binder for producing shaped articles having constant dielectric properties. 本发明涉及一种用于生产组合物的方法，其中使a)选自羟基封端的均聚的或共聚的聚苯醚和酚的化合物与b)单独或与式(IV)的二硅氧烷混合的式(I)氯硅烷在水和溶剂的存在下反应，R1aR2bSiCl4-a-b(I)，[R1(3-b)R2bSi]2O(IV)，其中R1、R2、a和b如权利要求1所定义；涉及通过该方法可获得的组合物；以及涉及所述组合物用作用于生产具有恒定介电性能的成型制品的粘结剂的用途。
