The mono-, bis-, tris-, and tetrakis(trimethylsilylmethyl)silanes, (Me3SiCH2)(x)SiH4-x (x = 1-4), have been prepared for use as "models" of the various Si-centered functional units in a complex, highly branched polycarbosilane polymer of the approximate composition, "(SiH2CH2)n". These compounds have been characterized by GC, IR, H-1, C-13, Si-29 NMR, MS, and elemental analysis. The IR and NMR data for this series of compounds show distinct trends on increasing substitution, which are related to the structural differences within the series.
