產(chǎn)品用途
一種氫封端的二硅氧烷,能和不飽和烯烴發(fā)生加成反應(yīng),因此廣泛用來(lái)制備氫封端的聚硅氧烷,用作硅橡膠的擴(kuò)鏈劑或交聯(lián)劑;或用于合成各種具有反應(yīng)活性官能團(tuán)封端的硅氧烷聚合物,用作有機(jī)聚合物的有機(jī)硅共聚改性。還可用作有機(jī)合成中的還原劑。
A hydrogen-terminated disiloxane, which can undergo an addition reaction with unsaturated olefins, so it is widely used in the preparation of hydrogen-terminated polysiloxane, as a chain extender or cross-linking agent for silicone rubber; or in the synthesis of various reactions Siloxane polymers terminated with sex functional groups for the co-modification of organic polymers with silicones. It can also be used as a reducing agent in organic synthesis.
