| 摘 要： | 利用辣根过氧化物酶(HRP)/H2O2催化体系合成对羟基苯甲醛(PHB)和对羟基苯磺酸钠(PHS)的共聚物。首先,PHB和乙二醇反应生成对羟基苯甲醛乙二醇缩醛(PHBEA)以保护醛基,然后进行PHBEA和PHS酶催化聚合,最后在酸性条件下解除缩醛得到PHB-PHS共聚产物。研究了单体摩尔比、体系pH、反应温度、HRP用量和H2O2滴加时间对PHBEA和PHS共聚反应的影响。用FTIR、NMR、GPC表征了产物结构。应用结果表明,应用革收缩温度(Ts)从54℃(鞣制前)提高至74.5℃(鞣制后)。该产物具有助染、鞣制等性能。

| Abstract: | The copolymer of p-hydroxybenzaldehyde(PHB) and 4-phenolsuflonate(PHS) was synthesized using the horseradish peroxidase(HRP)/H2O2 as catalyst.Firstly,PHB can react with ethylene glycol to generate p-hydroxybenzaldehyde ethylene acetal(PHBEA) so as to protect aldehyde group.Then,the copolymer of PHBEA and PHS was prepared by enzymatic catalytic polymerization.Finally,the copolymer of PHB-PHS was obtained by getting rid of the aldolization.Effects of the monomer composition,system pH,polymerization temperatur... |
