Abstract
Silyl derivatives of eugenol include compositions of the formula ##STR1## where R.sup.1, R.sup.2 and R.sup.3 are independently selected from linear, branched, and cyclic hydrocarbon groups having a total of from one to about eight carbon atoms, except that where one of R.sup.1, R.sup.2 or R.sup.3 is a phenyl group, the total of carbon atoms must be at least nine. They may be made by silylating the corresponding hydroxyl compound. They are useful as comonomers for olefins to introduce functional sites and may be copolymerized in Ziegler-Natta catalyst systems.
