Abstract
Abstract The mono-, bis-, tris-, and tetrakis(trimethylsilylmethyl)silanes, (Me3SiCH2)xSiH4−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, 1H, 13C, 29Si 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.
