## SYNOPSIS New polyimides containing diamantane units were prepared by a conventional two-step method starting from 1,6-diaminodiamantane and aromatic dianhydrides. The intermediate poly(amic acid)s had inherent viscosities of 0.33-0.55 dL/g. These polyimides did not decompose below 400°C in air
## Abstract 1,2‐Bis(__p__‐aminophenyl)tetramethyldisilane was synthesized from 1,2‐dichlorotetramethyldisilane and 4‐[__N,N__‐bis(trimethylsilyl)amino]phenyllithium. The diamine was reacted with various aromatic diacid chlorides giving disilane‐containing aromatic polyamides (aramids), whose inhere
