NOVEL THERMOSETS: MOLECULAR WEIGHT OF LIGNIN- PHENOL RESINS CATALYZED SYNTHESIS BY PEROXIDASE IN REVERSED MICELLAR SYSTEMS

在反相微乳液系统中进行了过氧化物酶催化木素与酚共聚反应实验,结果表明,聚合物重均分子量可以用活性剂浓度、酶浓度、单体浓度、油相中醇烃比来调控。用非线性优化方法关联了实验数据,得到了聚合物重均分子量的关联式。

The copolymerization of lignin with cresol in the reversed micellar systems by horseradish peroxidase as catalyzer was reviewed. The result shows that the maximal mean molecular weight of copolymer is 1890000. The size of the resulting copolymers can be controlled to great degree by adjusting the surfactant concentration and other factors. A correlation for copolymer mean molecular weight has been developed.
