BP/THF引发体系引发降冰片烯与马来酸酐可见光自由基共聚合

摘要

The characteristics of the visible radical photopolyrnerization of norbomene (NB) with maleic anhydride (MA) initiated by benzophenone/THF were studied. The effects of monomer concentration, atmosphere, initiator concen-tration and the third comonomer on the yield of copolymerization were investigated. The copolymer structure was charac-terized by IR,NMR,GPC and elemental analysis. The copolymer was a product of high alternation, and the content of NB and MA were 54.0% and 46.0% respectively, when n(MA)(NBE)= 1.%研究了BP/THF引发体系引发降冰片烯(NB)与马来酸酐(MA)自由基光聚合性能.考察了单体和引发剂浓度、第三单体的加入和氛围对共聚合收率的影响.采用红外光谱(FTIR)、核磁共振谱(NMR)、元素分析和高效凝胶液相色谱(GPC)对聚合物进行了表征与分析.在单体比为1:1时,共聚物中NB和MA的含量分别为54.2%和47.8%.
