8-丙烯酰氧喹啉及其聚合物与四溴化碳双组分体系敏化的丙烯腈光聚合

Photopolymerization of acrylonitrile (AN) sensitized by binary component initiators consisting of 8-acryloyloxyquinoline (AQ) and its polymer (PAQ) with carbon tetrabromide (CTB) are investigated kinetically. It is found that the polymerization rates are proportional to 0.19th power of AQ concentration, 0.35th power of CTB concentration and 0.62th power of AN concentration for AQ-CTB system initiation system; proportional to 0.24th power of PAQ concentration, 0.22th power of CTB concentration and 1.0th power of AN concentration initia-ted by above systems are obtained to be 5.26Kcal/mol and 6.34Kcal/mol respectively. It is also found that the polymerization rates sensitized by addition of CTB to AQ or PAQ are much higher than that ofAQ or PAQ alone. Forom the fluorescence analysis of AN polymers,it is confirmed that AQ or PAQ joints into the AN polymer chains. The molecular weight of PAN sensitized by the binary initiatorsystems is lower than that of AQ or PAQ sensitized.
