摘要 |
PURPOSE:To prepare the title polysilane which is sol. in an org. solvent and useful as a photoresist, a waveguide material. etc., by condensing p-n- butylphenyl-o-methylphenyldichlorosilane in the presence of metallic sodium. CONSTITUTION:p-n-Butylphenyl-o-methylphenyldichlorosilane is condensed in the presence of metallic sodium to give the title polysilane of the formula (wherein (n) is a mean degree of polymn.) which is sol. in an org. solvent and has no strong ultraviolet absorption band characteristic of an Si-Si chain near 300-400nm. |
