摘要
基于在“一步法”聚合反应过程中发现的酚酞对反应有特殊的“自催化”作用,本文合成了几种具有与酚酞类似结构的Cardo双酚,并通过对其聚合反应规律的研究,进一步探讨“自催化”作用的本质。实验结果表明,这类Cardo双酚也较普通结构双酚更易于进行异相成盐反应,表现为其聚合反应速度的明显加快。
Three cardo bisphenols (phenolphalan, phenolphthalimidine and N-methyl-phenolphtha-limidinr) were used to synthesize new polyaryl ether sulfones. The effect of the structuresof various cardo groups on the polycondensation was investigated to provide further expe-rimental evidence for mechanistic study. The results show that all these cardo bisphenolshave a polycondensation behavior similar to phenolphthalein, i.e. the rates of polymer for-mation are much greater than those of polymers from common bisphenols, such as Bisphe-nol-A or Bisphenol-S. The structures of these cardo polymers Were characterized by IRand ^(13)C NMR methods.
