Abstract
A curable composition containing (A) a polyene having at least two hydrosilation reactive carbon-carbon double bonds; (B) a cyclic silicon compound, having at least two hydrosilation reactive .tbd.SiH groups; and (C) a linear silicon compound containing at least two .tbd.SiH groups, and having the general formula: ##STR1## wherein R comprises at least one member selected from a group consisting of hydrogen, a substituted or unsubstituted saturated alkyl radical, and a substituted or unsubstituted phenyl radical, and R' comprises at least one member selected from a group consisting of hydrogen, a substituted or unsubstituted saturated alkyl radical, and a substituted or unsubstituted phenyl radical; m is an integer from about 25 to 1000, at least one R' is hydrogen; and the linear silicon compound is present in an amount of from about 5 to 95 weight percent, based on a total weight of silicon compounds present in the curable composition. The curable composition can contain a prepolymer. A cured composition comprises the reaction product formed upon subjecting the curable composition to conditions for polymerizing the polyene and the silicon compounds.
