摘　　要：在二氧化氮引发下完成了丙烯酸的聚合反应 ,研究了引发剂的浓度、单体浓度及温度对聚合反应的影响 ,求出聚合反应的表观活化能为 35 k J/mol,测定了聚合物的特性粘度 ,计算出聚合物的平均分子量 。Using NO 2 as initiator and TCE as solvent,the polymerization of acrylic acid was carried out. The effects of initiator concentration, monomer concentration and temperature on polymerizaticon were studied.The overall activation energy of polymerization was found to be 35 kJ/mol. The inberent viscosity of polymers was determinated and the average molecular weights of polymers were calculated. A radical mechanism is proposed for the polymerization.
