摘要： 70年代初苏联学者首次报道了聚硅乙炔烷的合成[1],1973年有人用炔化钙和二甲基二氯硅烷在熔融盐中反应,结果得到四环体物(Me2SiC≡C)4[2]。为了研究这类聚合物的性能,我们采用了新的合成路线合成可熔的聚硅乙炔烷。乙炔和格氏试剂发生交换反应,生成炔基双格氏试剂,它和有机二氯硅烷发生缩聚反应,生成聚硅乙炔烷。

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.

Key words: Poly(silanacetylene), Grignard reagent, Alternating copolymerization
