在反相微乳液系统中 ,进行了过氧化物酶催化木质素与酚共聚反应实验 ,考察了酶浓度、WO(水 /表面活性剂 ,质量比 )、表面活性剂浓度、单体 (酚、木质素 )浓度及醇烃比对聚合物分子量的影响。结果表明 ,聚合物重均分子量可用表面活性剂浓度、酶浓度、单体浓度及油相中醇烃比来调控。用单纯形优化法关联了实验数据 ,得到了聚合物重均分子量的关联式 :M =6 2 7× 10 4 (Y1× 10 7) -0 .3 4Y0 .982 Y0 .83 Y2 .4 64 Y1.0 55。聚合物分子量分布出现双峰 ,是两种反应机理竞争的结果。
In the reverse microemulsion system, the peroxidase catalyzed copolymerization of lignin and phenol was investigated. The effects of enzyme concentration, WO (water / surfactant, mass ratio), surfactant concentration, Lignin) concentration and the ratio of alcohol to polymer on the molecular weight of the polymer. The results showed that the weight average molecular weight of the polymer can be controlled by surfactant concentration, enzyme concentration, monomer concentration and the ratio of alcohol to hydrocarbon in the oil phase. The simplex method was used to correlate the experimental data and the weight average molecular weight was obtained: M = 6 2 7 × 10 4 (Y1 × 10 7) -0.3 4Y0 .982 Y0 .83 Y2 .4 64 Y1 .0 55. The bimodal distribution of the molecular weight of the polymer is the result of competition between the two reaction mechanisms.
