Polymethylsilane (PMS) is the simplest polysilane;it can be synthesized by Wurtz reductive coupling reaction of methyldichlorosilane in different solvent systems. The FT-IR
UV
1H-NMR
29Si-NMR spectra of PMS indicated that the resulting polymers showed Si—CH2—Si segments formed by the Kumada rearrangement when THF/n-hexane was used as solvent
and the Kumada rearrangement can be avoided by the stabilization effect on the silyl radicals when toluene was used as solvent.End-group of the polymer is changeable
and it is optimal to use Me3SiCl as end-blocking agent at a ratio of Me3SiCl/MeHSiCl2=0.045:1.
