The copolymerization of a small amount of the larger (C 2 B 8 and C 2 B 10 ) carboranes with the smaller C 2 B 5 carborane resulted in the formation of an elastomeric SiB‐1 carboranesiloxane, a polymer hitherto prepared only in crystalline form. Although the elastomeric behavior of the uncured SiB‐1 copolymer decreased with time, curing stabilized the rubber by inhibiting crystallization.
