SYNTHESIS, CHARACTERIZATION, AND STRUCTURAL INVESTIGATION OF POLY(DIETHYLSILYLENE)
S. DHUMRONGVARAPORNa AND H. KYOTANIb
ABSTRACT: Poly(diethylsilylene) was synthesized by dechlorination of diethyldi-chlorosilane with 40% sodium dispersed in mineral oil. Toluene was employed as a solvent. The polymer was characterized by FT-IR and NMR spectroscopies. Preliminary investigation of its structure was studied by GPC, DSC, X-Ray diffractions, and UV spectroscopy. The yield and molecular weights were found to depend on the reaction condition. The polymer was also found to be highly crystalline, and the higher molecular weight one gave the higher order-disorder transition temperature and the higher wavelength number of UV absorption maximum. The highest molecular weight one was insoluble in any kind of solvents.
