ABSTRACT:
Organopolysiloxane compositions which react by way of a hydrosilylation reaction to undergo an increase in viscosity have improved resistance to reaction at room temperature (longer pot life) and/or an improved reaction rate at elevated temperature (shorter cure time) than analogous compositions of the art by incorporating therein an unsaturated hydrocarbon having from 6 to 10 carbon atoms, a terminal acetylenic linkage and an olefinic linkage conjugated therewith. The resulting compositions are useful for preparing various cured siloxanes such as resins, elastomers, gels and foams.
