木质素-对甲酚共聚物的制备与分析

PREPARATION AND ANALYSIS OF LIGNIN AND P CRESOL COPOLYMER

采用了一种全新的反相微乳液体系，十六烷基三甲基溴化铵＼正丁醇＼异辛烷＼水，用辣根过氧化物酶催化合成木质素对甲酚共聚物，证实了反应的可行性。红外光谱的结果表明：木质素与对甲酚发生了聚合反应。差示扫描量势分析的结果表明，引入对甲酚改善了木质素的热性能。

Peroxidase catalyzed copolymerization of P cresol with lignin in reverse microemulsion is carried out. The result shows that the new reverse microemusion system; CTAB\n Butanol\isooctane\water, is capable of catalyzing the synthesis of lignin and P cresol copolymer. Lignin and P cresol react each other from Infrared spectrum of the coploymer. DSC shows that the thermal property of copolymer is better than that of lignin by introducing P cresol into copolymer.
