ORGANOMETTALIC POLYMERS
Abstract
Continued investigation of stannosiloxane polymers has led to the conclusion that relatively large organic substituents must replace the triethyl and phenyl groups thus far studied, if high thermal stability is to be obtained. The polyorganostannosiloxanes have been found to undergo extensive decomposition and disproportionation on prolonged heating above 300 C. Reactions of organotin disodium derivatives with organic dihalides to prepare linear polymers containing tin-carbon chains are described. A very convenient method is reported for the preparation of tin-sulfur polymers (stanthianes) by reaction of sulfur with divalent organotin compounds. Explorations have been initiated to prepare aluminum oxide polymers. The thermal stability of the aluminum-oxygen bond should lead to polymers of improved heat and oxidative stability. The extreme reactivity of the aluminum-alkyl bond has been utilized in an effort to obtain high molecular weights.
