Multivinyl Silicone Oil

Chemical Name: Vinyl-terminated & Pendant Vinyl Polydimethylsiloxane CAS No. 68083-19-2 / 68951-99-5

Multivinyl Silicone Oil is synthesized via the ring-opening polymerization and equilibration process from tetramethyldivinyldisiloxane, vinyl cyclosiloxanes and dimethyl cyclosiloxanes. Its molecular structure has a prominent characteristic: it contains vinyl reactive groups not only at both ends of the molecular chain, but also on partial chain links. This special structure endows it with excellent reactivity. It can undergo addition reactions with other organic compounds (e.g., polymers with reactive or hydride groups), and can also form silicone elastomers under the catalysis of peroxides. Such unique chemical properties make it an important material for applications across diverse industries.
