Abstract

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.
