application | organosilicon compounds containing (meth) acryloxy can undergo free radical polymerization with monomers such as (meth) acrylate and styrene to obtain various organosilicon modified polymers, which is an organic intermediate with a wide range of applications. Among them, methacryloyl propyl dimethylchlorosilane is the most common, and it is often used as a capping agent and modifier. |
Preparation | In recent years, methacryloyl propyl dimethylchlorosilane has been paid attention to by researchers at home and abroad. The commonly used synthesis method is dimethylchlorosilane (CDMS) and allyl methacrylate (AMA) are directly prepared by hydrosilylation. In this paper, a highly active catalyst was synthesized on the basis of the existing work, which was used to catalyze the hydrosilylation reaction of allyl methacrylate and dimethylchlorosilane to synthesize methacryloxypropyl dimethylchlorosilane. The reaction temperature was reduced by more than 25 ℃ compared with the classical Speier catalyst, and the yield could still reach about 80%. |
