ABSTRACT:
Certain liquid polydiorganosiloxanes wherein each molecule contains at least one sequence of 2 or more vinyl radicals bonded to non-terminal silicon atoms extend the working time at 25.degree. C. of organosiloxane compositions that cure by a platinum catalyzed hydrosilation reaction without adversely affecting the cure rate of the composition at temperatures of about 100.degree. C. and above. The polydiorganosiloxane is prepared by the acid-catalyzed polymerization of the corresponding cyclic polydiorganosiloxanes in the presence of a chain-terminating organosilicon reactant.
