高分子醛类分子式:CAS号:性质:指含有端醛基(—CHO)的高分子。聚合物中的醛基可以通过高分子化羧酸经控制还原,或者直接由带有可聚合基团的小分子醛经聚合或接枝反应得到。醛的化学活性较强,能和多种化合物发生化学反应,如与醇反应生成缩醛或半缩醛;与羟胺和酰肼反应生成肟和腙,醛基还具有氧化和还原反应能力。高分子醛类可以和带有羟基的化合物反应生成缩醛或半缩醛,以醚键的形式将小分子化合物与高分子骨架结合,用来引入功能结构或者在有机合成反应中保护羟基。高分子骨架上的醛基通过氧化或者还原反应,可以转化成羧基或者羟基,而上述基团可以与多种化合物进行酯化反应,用于将小分子引入,构成功能高分子,或者作为固相合成试剂。
