摘要: 高分子化合物沿分子链(主链和侧链)排列多量可离解基团(每个链节可有1~2个)称聚电解质或聚离子[1]。聚电解质在水中可离解成两部分,若离解后,聚合物链带负电荷,称聚阴离子电解质或聚负离子;若带正电荷,称聚阳离子电解质或聚正离子。

Abstract: Polyion complexes based on diazo-resin were prepared from the reaction between diazo-resin as polycation and poly(sodium 4-styrene sulfonate) as polyanion in aqueous solution. The polyion complexes containing diazonium groups exhibit high photosensitive behaviors. Under irradiation of UV light, the complex, which dissolves in the shielding solvent composed of DMF-H2O LiCl, will become indissoluble because the complex changes its crosslinking structure from ionic link to covalent bond. This character should be very important to develop a new photoimaging system.

Key words: diazo-resin, poly(sodium 4-styrene sulfonate), polyion complex
