Abstract : The objective of the program is to develop syntheses for thermally and hydrolytically stable elastomers based on chains containing silicon atoms bonded directly to nitrogen, and to conduct preliminary evaluation of the materials obtained. 2,2-Dimethyl-1,3-bis (chlorodimethylsilyl)-1,3-diaza-2-silacyclopentane (I) and the corresponding diazasilacyclohexane (II) derivative were prepared. Products from the interaction of dichlorodiphenylsilane and dichloromethylphenylsilane with ethylenediamine, 1,3-propylenediamine, and o-phenylenediamine were obtained. The NH3, MeNH2, and aniline derivatives of I and II have also been prepared and tentatively identified. The report includes a review of the literature on Si-N polymers. (Author)
