In this work, the preparation of α, ω-dichloride-terminated multi-vinyl branched siloxane 1 (yield: 57.1%) used for self-healing polymer composites were synthesized via ring-opening of 1,3,5,7-tetravinyl-1,3,5,7-tetramethyl-cyclotetrasiloxane (D4Vi) in the presence of vinylmethydichlorosilane (VM-32). I was hydrogenated by aluminum lithium hydride (LiAlH4) to get self-healing monomer 2 (yield: 79.8%) which contained both Si-H bonds and Si-vinyl bonds. Then hydrosilation occurred between these two bands and finally silicone 3 was obtained, showing the potential of self-healing.
