研究了金属镁在硝酸溶液中引发丙烯腈的聚合反应。实验结果表明,聚合速度与金属镁的用量无关,并且当[HNO_3]>[AN]时服从下列关系式: R_p=1.91×10~5e~(-15000/RT)[Mg]~0[AN]~(2.2)[HNO_3]~(0.45) 丙烯腈-丙烯酸甲酯的共聚试验证明,聚合反应是按自由基机理进行。
The polymerization of acrylonitrile initiated by metallic magnesium in nitric acid solution was studied. The experimental results show that the polymerization rate has nothing to do with the amount of magnesium metal, and when [HNO_3]> [AN], the following relationship: R_p = 1.91 × 10-5e ~ (-15000 / RT) [Mg] ~ 0 [AN] ~ (2.2) [HNO3] ~ (0.45) copolymerization of acrylonitrile - methyl acrylate test proved that the polymerization reaction is based on the free radical mechanism.
