| 摘 要： | 以α-溴代异丁酸叔丁酯为引发剂，二乙烯苯为支化单体，苯乙烯为共聚单体，经原子转移自由基聚合原位生成自引发单体合成支化共聚物。用核磁共振法、凝胶渗透色谱法、三角激光散射法分别对聚合过程和聚合物进行了表征。结果表明：由于苯乙烯的引入，反应体系的交联得到了很好的控制，所得聚合物为支化结构。

| Abstract: | The authors studied the self-condensing vinyl copolymerization of styrene and inimer which is formed in- situ via atom transfer radical polymerization with divinylbenzene as branching monomer in the presence of 2- bromoisobutyl-tert-butyrate as initiator.Proton nuclear magnetic resonance (~1H-NMR) spectroscopy and gel permeation chromatography (GPC) coupled with tri-angle laser light scattering (MALLS) were used to monitor the polymerization process and characterize the resultant polymers.The results indica... |
