摘要
合成了功能性单体N - (对苯氧基苯基 ) -甲基丙烯酰胺 (MAPOA)及其聚合物 (P(MAPOA) ) .研究了MAPOA引发丙烯腈 (AN)的光聚合行为 ;测得的光聚合的动力学和活化能分别为Rp([MAPOA]0 .3 8[AN]0 .78和Ea =2 4.2kJ mol;通过对MAPOA引发丙烯腈光聚合产物的荧光分析发现 ,MAPOA不仅参与光引发而且还参与聚合反应 ,其自身进入到聚合物链中 ;对MAPOA及其聚合物的荧光光谱研究表明 ,MAPOA引发丙烯腈光聚合是通过光诱导电荷转移产生自由基引发的机制进行的 .
A novel acrylic monomer bearing acromatic ethereality group N-(p-Phenoxy-phenyl)Methacrylamide (MAPOA) was synthesized and polymerized. The photopolymerization of AN sensitized by MAPOA was studied kinetically.The kinetic equation and overall activation energy went respectively as follows: R p([MAPOA] 0.38 [AN] 0.78 and E a=24.2 kJ/mol. On the ground of the analysis of fluorescence intensity of PAN sensitized by MAPOA,it was confirmed that MAPOA not only sensitized the photopolymerization of AN but also entered into the PAN chains.The photochemical behaviors of MAPOA and its polymer were explored by recording the fluorescence spectra.A mechanism of charge transfer complex(CTC) formation and free radical initiation was suggested for the photopolymerization of AN sensitized by MAPOA.
