They can be used to obtain resins, lacquers, liquids, rubbers with enhanced thermal-oxidative stability. A method is known for preparing this compound by reacting organochlorosilanes with o-chlorophenyls at 500-700 ° C. The advantages of such a method are to carry out the synthesis at high temperatures (700 ° C), a significant percentage of bottom fraction, and the use of trichlorosilane (the ratio between o-chloridiphenyl and trichlorosilane is at least 1: 2). | |
