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 (D₄^Vi) in the presence of vinylmethydichlorosilane (VM-32). 1 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.
