SYNTHESIS OF ELASTOMERS CONTAINING SI-N BONDS IN THE MAIN CHAIN.
Abstract
Rubbery products were obtained when silazane-organic diol polymers are heated with compounds containing the cyclotriphosphazatriene ring, but it was not established that the polymers are crosslinked by these reagents. Two new polymers were prepared from cyclotrisilazanes containing ethyl and benzyl groups. Although both polymers had good hydrolytic stability, thermal stability was poor. A detailed examination of the thermal and oxidative stability showed that a nonamethylcyclotrisilazane-bisphenol 'A' polymer was thermally stable at 300C, but underwent oxidative degradation at that temperature.
