| 摘 要： | 用紫外吸收光谱和荧光光谱分析了苯胺等芳胺引发光聚合的聚丙烯腈和聚甲基丙烯酸甲酯的端基,认为一级胺引发的聚合物端基为二级胺,二级胺引发的聚合物端基为三级胺,从而表明,一级芳胺和二级芳胺在光照下与烯类单体相互作用产生氮自由基引发聚合。

| Abstract: | The end-groups of the polymers formed in photopolymerization initiated by aromatic amines,such as aniline,were identified with electron and fluorescence-spectro-photometric methods. The spectra show the presence of secondary and tertiary amino end-groups in the polymers formed with primary and secondary amine as initiators,respectively. These results suggest that the nitrogen radicals of the aromatic (primary and secondary amines,which were produced from the proton transfer in the exciplexes between amines and vinyl monomers,are also responsible for the initiation. |
