Abstract: The poly (diphenylsilanacetylene) ( Ⅰ ),poly (dimethylsilanacetylene) (Ⅱ ) and random copolymer of diphenylsilanacetylene and dimethylsilanacetylene ( Ⅲ ) were prepared via the condensation reaction between BrMgC≡CMgBr and R2SiCl2. The polymer can be dissolved in common organic solvents such as toluene,THF,and can be casted in films or drawn into fibers when melting except for ( Ⅲ ). The structures of polymers have been characterized by IR, 1H NMR, UVspectrometry and VPOmethods. The thermal stability and electroconductivity of these polymers were studied preliminarily.
