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%。
The free radical photopolymerization of norbornene (NB) with maleic anhydride (MA) initiated by BP / THF initiator system was studied. The effects of the monomer and initiator concentration, the addition of the third monomer and the atmosphere on the copolymerization yield were investigated. The polymers were characterized and analyzed by infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR), elemental analysis and high performance gel permeation chromatography (GPC). At the monomer ratio of 1: 1, the contents of NB and MA in the copolymer were 54.2% and 47.8%, respectively.
