摘　　要：采用膨胀计法,研究了N 乙烯基吡咯烷酮(NVP)和甲基丙烯酸 羟乙酯(HEMA)本体共聚[过氧化二苯甲酰(BPO)为引发剂]反应过程。由动力学分析得到引发剂的反应级数和单体反应总级数分别为0.8437和2,其共聚反应的表观活化能Ea=53.34kJ/mol。The kinetics of pure copolymerization of NVinylpyrrolidone(NVP) and 2hydroxyethyl methacrylate(HEMA) has been studied systematically by a dilatometer with benzoylperoxide(BPO) as initiator.Through a series of experiments,we obtain the order of initiator and the total order of monomers,their values are 0.843?7and 2 respectively.The activative energy of copolymerization has been measured meanwhile,and Ea=53.34?kJ/mol.
