|Title:||SYNTHESIS AND CHARACTERIZATION OF SOME POLY-P-SILPHENYLENES|
|Abstract:||The syntheses of some representative low molecular weight poly-p-silphenylenes containing SiMe2 or SiPh2 groups in the main chain are presented. These polymers were obtained from di-Grignard intermediates using either THF or Et2O as solvent. The insertion of the butylenoxy units in the main chains of the polymers was observed when THF was used as a solvent. The polymers were characterized by a combination of IR, H-1 and C-13 - NMR spectra and vapour pressure osmometric analysis. The thermal behaviour of the poly-p-silphenylenes was analysed by thermogravimetry.|
