The copolymerization of a small amount of the larger (C2B8 and C2B10) carboranes with the smaller C2B5 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.
少量较大的(C 2 B 8和C 2 B 10)碳
硼烷与较小的C 2 B 5碳
硼烷的共聚导致形成弹性体SiB-1碳
硼烷硅氧烷,这是迄今为止仅以结晶形式制备的聚合物。尽管未固化的SiB-1共聚物的弹性行为随时间降低,但固化通过抑制结晶作用使橡胶稳定。
