摘　　要：采用可逆加成裂解链转移自由基聚合（RAFT）制备偶氮苯聚合物,通过红外光谱仪、核磁共振氢谱仪对聚合物的结构进行表征,结果表明已成功地合成出目标产物。通过GPC凝胶渗透色谱仪）对其分子量进行测试,表明合成出的聚合物的分子量分布（PDI）为1.01~1.05,聚合物的分子量随反应时间的延长不断增长,呈现出＂活性-可控＂聚合特征。Pstyrene was prepared using reversible addition-fragmentation chain transfer polymerization （ RAFT） with living polymerization. The structure of polymers were characterized by the infrared spectroscopy （ FTIR ） , Hydrogen nuclear magnetic resonance spectrometer （ 1 H-NMR ） , and the result showed that the desired product was synthesized successfully. Using the Gel permeation Chromatograph （ GPC ） for testing the molecular weight, it was indicated the molecular weight distribution of the polymer （ PDI ） synthesized was 1. 01 ~1. 05 , and as the molecular weight of the polymer with the constant change of reaction time, a trend of variation showed, as realizing the “active-controllable” .
