Abstract:

A number of oligomeric p-phenylenesilanes containing 2-6 silicon atoms per molecule and a series of low molecular weight poly-p-phenylenesilanes n - 10-30 were prepared by Wurtz-type condensation reactions involving appropriate combinations of p-chlorophenyl- and chlorosilanes. The polymeric products were characterized by infrared spectroscopy, analytical and thermogravimetric data, and number-average molecular weights, the low value of which is presumably caused by participation of the solvent toluene in the reaction. The polymers started to lose weight at temperatures varying from 310C to 485C. Author
