摘要

NOVEL ORGANOSILOXANE INHIBITORS FOR HYDROSILATION REACTIONS AND POLYORGANOSILOXANE COMPOSITIONS CONTAINING SAME Liquid polydiorganosiloxanes wherein the molecules contain at least one sequence of two or more non-terminal siloxane units with a silicon-bonded vinyl radical extend the working time at 25.degree.C. of organosiloxane compositions curable by a platinum catalyzed hydrosilation reaction without adversely affecting the cure rate of said compositions at temperatures of at least about 100.degree.C.
