Summary Tetramethylcylcotetrasiloxane (D4H) was hydrosilylated with α,α′-dimethyl meta-isopropenyl benzyl isocyanate (m-TMI). The reaction with this commercially available and inexpensive isocyanate produces in 100% yield a well characterized tetrafunctional siloxane-based aliphatic isocyanate useful as a cross-linking agent and as a precursor for star polymers. The silylation reaction can also be carried out with other siloxanes containing SiH groups such as 1,1,3,3-tetramethyldisiloxane yielding siloxanes with terminal isocyanate groups.
