【Abstract】 With methylvinyldichlorosilane, methyldichlorosilane and various primary alkylhalides as starting agents, methyl （β-trialkylsilylethyl） dichlorosilanes were prepared via Grignard reaction and hydrosilation. New organosilane polymers containing β-trialkylsilylethyl side group were synthesized by sodium coupling of diorganodichlorosilares in toluene. The polymers of CH₃（R₃SiCH₂CH₂）SiCl₂ are flowable, and the copolymers of CH₃（R₃SiCH₂CH₂）SiCl₂ with CH₃PhSiCl₂ are elasto-viscous states. The structure and physical constants of organodichlorosilanes were determined, and the molecular weight, infrared, nuclear magnetic resonance and ultraviolet spectra for the organosilane polymers were described.更多还原
